+%%% @doc Type manipulation functions and predefined types.
+%%%
+%%% == Basic types ==
+%%% This module defines all the basic types of the PropEr type system as
+%%% functions. See the <a href="#index">function index</a> for an overview.
+%%%
+%%% Types can be combined in tuples or lists to produce other types. Exact
+%%% values (such as exact numbers, atoms, binaries and strings) can be combined
+%%% with types inside such structures, like in this example of the type of a
+%%% tagged tuple: ``{'result', integer()}''.
+%%%
+%%% When including the PropEr header file, all
+%%% <a href="#index">API functions</a> of this module are automatically
+%%% imported, unless `PROPER_NO_IMPORTS' is defined.
+%%%
+%%% == Customized types ==
+%%% The following operators can be applied to basic types in order to produce
+%%% new ones:
+%%%
+%%% <dl>
+%%% <dt>`?LET(<Xs>, <Xs_type>, <In>)'</dt>
+%%% <dd>To produce an instance of this type, all appearances of the variables
+%%% in `<Xs>' are replaced inside `<In>' by their corresponding values in a
+%%% randomly generated instance of `<Xs_type>'. It's OK for the `<In>' part to
+%%% evaluate to a type - in that case, an instance of the inner type is
+%%% generated recursively.</dd>
+%%% <dt>`?SUCHTHAT(<X>, <Type>, <Condition>)'</dt>
+%%% <dd>This produces a specialization of `<Type>', which only includes those
+%%% members of `<Type>' that satisfy the constraint `<Condition>' - that is,
+%%% those members for which the function `fun(<X>) -> <Condition> end' returns
+%%% `true'. If the constraint is very strict - that is, only a small
+%%% percentage of instances of `<Type>' pass the test - it will take a lot of
+%%% tries for the instance generation subsystem to randomly produce a valid
+%%% instance. This will result in slower testing, and testing may even be
+%%% stopped short, in case the `constraint_tries' limit is reached (see the
+%%% "Options" section in the documentation of the {@link proper} module). If
+%%% this is the case, it would be more appropriate to generate valid instances
+%%% of the specialized type using the `?LET' macro. Also make sure that even
+%%% small instances can satisfy the constraint, since PropEr will only try
+%%% small instances at the start of testing. If this is not possible, you can
+%%% instruct PropEr to start at a larger size, by supplying a suitable value

+%%% <dt>`?SUCHTHATMAYBE(<X>, <Type>, <Condition>)'</dt>
+%%% <dd>Equivalent to the `?SUCHTHAT' macro, but the constraint `<Condition>'
+%%% is considered non-strict: if the `constraint_tries' limit is reached, the
+%%% generator will just return an instance of `<Type>' instead of failing,
+%%% even if that instance doesn't satisfy the constraint.</dd>
+%%% <dt>`?SHRINK(<Generator>, <List_of_alt_gens>)'</dt>
+%%% <dd>This creates a type whose instances are generated by evaluating the
+%%% statement block `<Generator>' (this may evaluate to a type, which will
+%%% then be generated recursively). If an instance of such a type is to be
+%%% shrunk, the generators in `<List_of_alt_gens>' are first run to produce
+%%% hopefully simpler instances of the type. Thus, the generators in the
+%%% second argument should be simpler than the default. The simplest ones
+%%% should be at the front of the list, since those are the generators
+%%% preferred by the shrinking subsystem. Like the main `<Generator>', the

+%%% <dt>`?LETSHRINK(<List_of_variables>, <List_of_types>, <Generator>)'</dt>
+%%% <dd>This is created by combining a `?LET' and a `?SHRINK' macro. Instances

+%%% `<Generator>' (just like a `?LET', with the added constraint that the
+%%% variables and types must be provided in a list - alternatively,
+%%% `<List_of_types>' may be a list or vector type). When shrinking instances

+%%% be generated recursively). Using this, you can simulate the lazy
+%%% generation of instances:
+%%% ``` stream() -> ?LAZY(frequency([ {1,[]}, {3,[0|stream()]} ])). '''
+%%% The above type produces lists of zeroes with an average length of 3. Note

+%%% == Size manipulation ==
+%%% The following operators are related to the `size' parameter, which controls
+%%% the maximum size of produced instances. The actual size of a produced
+%%% instance is chosen randomly, but can never exceed the value of the `size'
+%%% parameter at the moment of generation. A more accurate definition is the
+%%% following: the maximum instance of `size S' can never be smaller than the
+%%% maximum instance of `size S-1'. The actual size of an instance is measured
+%%% differently for each type: the actual size of a list is its length, while
+%%% the actual size of a tree may be the number of its internal nodes. Some
+%%% types, e.g. unions, have no notion of size, thus their generation is not
+%%% influenced by the value of `size'. The `size' parameter starts at 1 and
+%%% grows automatically during testing.
+%%%
+%%% <dl>
+%%% <dt>`?SIZED(<S>, <Generator>)'</dt>
+%%% <dd>Creates a new type, whose instances are produced by replacing all
+%%% appearances of the `<S>' parameter inside the statement block
+%%% `<Generator>' with the value of the `size' parameter. It's OK for the
+%%% `<Generator>' to return a type - in that case, an instance of the inner
+%%% type is generated recursively.</dd>

+
+%%% @doc Erlang type system - PropEr type system integration module.
+%%%
+%%% PropEr can parse types expressed in Erlang's type language and convert them
+%%% to its own type format. Such expressions can be used instead of regular type
+%%% constructors in the second argument of `?FORALL's. No extra notation is
+%%% required; PropEr will detect which calls correspond to native types by
+%%% applying a parse transform during compilation. This parse transform is
+%%% automatically applied to any module that includes the `proper.hrl' header
+%%% file. You can disable this feature by compiling your modules with
+%%% `-DPROPER_NO_TRANS'. Note that this will currently also disable the
+%%% automatic exporting of properties.
+%%%
+%%% The use of native types in properties is subject to the following usage
+%%% rules:
+%%% <ul>
+%%% <li>Native types cannot be used outside of `?FORALL's.</li>
+%%% <li>Inside `?FORALL's, native types can be combined with other native
+%%% types, and even with PropEr types, inside tuples and lists (the constructs
+%%% `[...]', `{...}' and `++' are all allowed).</li>
+%%% <li>All other constructs of Erlang's built-in type system (e.g. `|' for
+%%% union, `_' as an alias of `any()', `<<_:_>>' binary type syntax and
+%%% `fun((...) -> ...)' function type syntax) are not allowed in `?FORALL's,
+%%% because they are rejected by the Erlang parser.</li>
+%%% <li>Anything other than a tuple constructor, list constructor, `++'
+%%% application, local or remote call will automatically be considered a
+%%% PropEr type constructor and not be processed further by the parse
+%%% transform.</li>
+%%% <li>Parametric native types are fully supported; of course, they can only
+%%% appear instantiated in a `?FORALL'. The arguments of parametric native
+%%% types are always interpreted as native types.</li>
+%%% <li>Parametric PropEr types, on the other hand, can take any kind of
+%%% argument. You can even mix native and PropEr types in the arguments of a
+%%% PropEr type. For example, assuming that the following declarations are
+%%% present:
+%%% ``` my_proper_type() -> ?LET(...).
+%%% -type my_native_type() :: ... .'''
+%%% Then the following expressions are all legal:
+%%% ``` vector(2, my_native_type())
+%%% function(0, my_native_type())
+%%% union([my_proper_type(), my_native_type()])''' </li>
+%%% <li>Some type constructors can take native types as arguments (but only
+%%% inside `?FORALL's):
+%%% <ul>
+%%% <li>`?SUCHTHAT', `?SUCHTHATMAYBE', `non_empty', `noshrink': these work
+%%% with native types too</li>
+%%% <li>`?LAZY', `?SHRINK', `resize', `?SIZED': these don't work with native
+%%% types</li>
+%%% <li>`?LET', `?LETSHRINK': only the top-level base type can be a native
+%%% type</li>
+%%% </ul></li>
+%%% <li>Native type declarations in the `?FORALL's of a module can reference any
+%%% custom type declared in a `-type' or `-opaque' attribute of the same
+%%% module, as long as no module identifier is used.</li>
+%%% <li>Typed records cannot be referenced inside `?FORALL's using the
+%%% `#rec_name{}' syntax. To use a typed record in a `?FORALL', enclose the
+%%% record in a custom type like so:
+%%% ``` -type rec_name() :: #rec_name{}. '''
+%%% and use the custom type instead.</li>
+%%% <li>`?FORALL's may contain references to self-recursive or mutually
+%%% recursive native types, so long as each type in the hierarchy has a clear
+%%% base case.
+%%% Currently, PropEr requires that the toplevel of any recursive type
+%%% declaration is either a (maybe empty) list or a union containing at least
+%%% one choice that doesn't reference the type directly (it may, however,
+%%% reference any of the types that are mutually recursive with it). This
+%%% means, for example, that some valid recursive type declarations, such as
+%%% this one:
+%%% ``` ?FORALL(..., a(), ...) '''
+%%% where:
+%%% ``` -type a() :: {'a','none' | a()}. '''
+%%% are not accepted by PropEr. However, such types can be rewritten in a way
+%%% that allows PropEr to parse them:
+%%% ``` ?FORALL(..., a(), ...) '''
+%%% where:
+%%% ``` -type a() :: {'a','none'} | {'a',a()}. '''
+%%% This also means that recursive record declarations are not allowed:
+%%% ``` ?FORALL(..., rec(), ...) '''
+%%% where:
+%%% ``` -type rec() :: #rec{}.
+%%% -record(rec, {a = 0 :: integer(), b = 'nil' :: 'nil' | #rec{}}). '''
+%%% A little rewritting can usually remedy this problem as well:
+%%% ``` ?FORALL(..., rec(), ...) '''
+%%% where:
+%%% ``` -type rec() :: #rec{b :: 'nil'} | #rec{b :: rec()}.
+%%% -record(rec, {a = 0 :: integer(), b = 'nil' :: 'nil' | #rec{}}). '''
+%%% </li>
+%%% <li>Remote types may be referenced in a `?FORALL', so long as they are
+%%% exported from the remote module. Currently, PropEr requires that any
+%%% remote modules whose types are directly referenced from within properties
+%%% are present in the code path at compile time, either compiled with
+%%% `debug_info' enabled or in source form. If PropEr cannot find a remote
+%%% module at all, finds only a compiled object file with no debug
+%%% information or fails to compile the source file, all calls to that module
+%%% will automatically be considered calls to PropEr type constructors.</li>
+%%% <li>For native types to be translated correctly, both the module that
+%%% contains the `?FORALL' declaration as well as any module that contains
+%%% the declaration of a type referenced (directly or indirectly) from inside
+%%% a `?FORALL' must be present in the code path at runtime, either compiled
+%%% with `debug_info' enabled or in source form.</li>
+%%% <li>Local types with the same name as an auto-imported BIF are not accepted
+%%% by PropEr, unless the BIF in question has been declared in a
+%%% `no_auto_import' option.</li>
+%%% <li>When an expression can be interpreted both as a PropEr type and as a
+%%% native type, the former takes precedence. This means that a function
+%%% `foo()' will shadow a type `foo()' if they are both present in the module.
+%%% The same rule applies to remote functions and types as well.</li>
+%%% <li>The above may cause some confusion when list syntax is used:
+%%% <ul>
+%%% <li>The expression `[integer()]' can be interpreted both ways, so the
+%%% PropEr way applies. Therefore, instances of this type will always be
+%%% lists of length 1, not arbitrary integer lists, as would be expected
+%%% when interpreting the expression as a native type.</li>
+%%% <li>Assuming that a custom type foo/1 has been declared, the expression
+%%% `foo([integer()])' can only be interpreted as a native type declaration,
+%%% which means that the generic type of integer lists will be passed to
+%%% `foo/1'.</li>
+%%% </ul></li>
+%%% <li>Currently, PropEr does not detect the following mistakes:
+%%% <ul>
+%%% <li>inline record-field specializations that reference non-existent
+%%% fields</li>
+%%% <li>type parameters that are not present in the RHS of a `-type'
+%%% declaration</li>
+%%% <li>using `_' as a type variable in the LHS of a `-type' declaration</li>
+%%% <li>using the same variable in more than one position in the LHS of a
+%%% `-type' declaration</li>
+%%% </ul>
+%%% </li>
+%%% </ul>
+%%%
+%%% You can use <a href="#index">these</a> functions to try out the type
+%%% translation subsystem.
+%%%
+%%% CAUTION: These functions should never be used inside properties. They are
+%%% meant for demonstration purposes only.

+<p>
+Defaults to <c>true</c>.</p>
+
+<warning>
+<p>
+RFC 6733 is unclear about the semantics of the M-bit.
+One the one hand, the CCF specification in section 3.2 documents AVP
+in a command grammar as meaning <b>any</b> arbitrary AVP; on the
+other hand, 1.3.4 states that AVPs setting the M-bit cannot be added
+to an existing command: the modified command must instead be
+placed in a new Diameter application.</p>
+<p>
+The reason for the latter is presumably interoperability:
+allowing arbitrary AVPs setting the M-bit in a command makes its
+interpretation implementation-dependent, since there's no
+guarantee that all implementations will understand the same set of
+arbitrary AVPs in the context of a given command.
+However, interpreting <c>AVP</c> in a command grammar as <b>any</b>
+AVP, regardless of M-bit, renders 1.3.4 meaningless, since the receiver
+can simply ignore any AVP it thinks isn't relevant, regardless of the
+sender's intent.</p>
+<p>
+Beware of confusing mandatory in the sense of the M-bit with mandatory
+in the sense of the command grammar.
+The former is a semantic requirement: that the receiver understand the
+semantics of the AVP in the context in question.
+The latter is a syntactic requirement: whether or not the AVP must
+occur in the message in question.</p>

+ <p>This parameter can be used to limit the size of the

+
+ <note><p>This configuration parameter was introduced in OTP 18.1.
+ It is currently experimental. Based on user feedback it
+ may be changed or improved in future releases, for example
+ to gain better control over how to limit the size of the
+ formatted output. We have no plans to entirely remove this
+ new feature, unless it turns out to be completely
+ useless. In OTP 19, the default may be changed to limit the
+ formatted output.</p></note>
+
+ <p><c>Depth</c> is a positive integer that is the maximum
+ depth to which terms are printed by the error logger event
+ handlers included in OTP. Specifically, the two event handlers
+ defined by the <c>Kernel</c> application and the two event
+ handlers in the <c>SASL</c> application will use this
+ configuration parameter. (If you have implemented you own
+ error handlers, this configuration parameter will have no
+ effect on them.)</p>
+
+ <p>The way <c>Depth</c> is used, is that format strings
+ string passed to the event handlers will be rewritten.
+ The "~p" and "~w" format controls will be replaced with
+ "~P" and "~W", respectively, and <c>Depth</c> will be
+ used as the depth parameter. See
+ <seealso marker="stdlib:io#format/2">io:format/2</seealso>.</p>
+
+ <note><p>A reasonable starting value for <c>Depth</c> is
+ <c>30</c>. You should test crashing various processes in your
+ application and examine the logs from the crashes, and then
+ either increase or decrease the value.</p></note>

+ <p>A mechanism for limiting the amount of text that the

+ New application variable to set timeout of internal
+ communication setup between the erlang code and the
+ c-port program that interfaces the odbc driver. This can
+ be useful if you have an underlying system that is slow
+ due to heavy load at startup.</p>
+ <p>
+ With this environment variable you can easily bypass and
+ tailor odbc to the needs of the underlying actual system
+ without changing the configuration. Which is a good thing
+ because this value is very system specific.</p>

+ <p>A mechanism for limiting the amount of text that the

+ introduced. It is useful for limiting both the size of
+ log files and the CPU time used to produce them.</p>
+ <p>This mechanism is experimental in the sense that it
+ may be changed if it turns out that it does not solve the
+ problem it is supposed to solve. In that case, there may
+ be backward incompatible improvements to this
+ mechanism.</p>

+ Add application setting to be able to change fatal alert

+ fatal alert timeout is the number of milliseconds between
+ sending of a fatal alert and closing the connection.
+ Waiting a little while improves the peers chances to
+ properly receiving the alert so it may shutdown

+ <p>A mechanism for limiting the amount of text that the

+ introduced. It is useful for limiting both the size of
+ log files and the CPU time used to produce them.</p>
+ <p>This mechanism is experimental in the sense that it
+ may be changed if it turns out that it does not solve the
+ problem it is supposed to solve. In that case, there may
