<funcs>
<func>
<name>decode(Module,Type,Bytes) -> {ok,Value}|{error,Reason}</name>
<fsummary>Decodes from Bytes into an ASN.1 value.</fsummary>
<type>
<v>Module = Type = atom()</v>
<v>Value = Reason = term()</v>
<v>Bytes = binary</v>
</type>
<desc>
<p>Decodes <c>Type</c> from <c>Module</c> from the binary <c>Bytes</c>.
Returns <c>{ok,Value}</c> if successful.</p>
<p>Use <c>Module:decode(Type, Bytes)</c> instead of this function.</p>
</desc>
</func>
<func>
<name>encode(Module,Type,Value)-> {ok,Bytes} | {error,Reason}</name>
<fsummary>Encodes an ASN.1 value.</fsummary>
<type>
<v>Module = Type = atom()</v>
<v>Value = term()</v>
<v>Bytes = binary</v>
<v>Reason = term()</v>
</type>
<desc>
<p>Encodes <c>Value</c> of <c>Type</c> defined in the <c>ASN.1</c>
module <c>Module</c>. Returns a binary if successful. To get
as fast execution as possible, the encode function performs
only the rudimentary test that input <c>Value</c> is a correct
instance of <c>Type</c>. For example, the length of strings is
not always checked.</p>
<p>Use <c>Module:encode(Type, Value)</c> instead of this function.</p>
</desc>
</func>
<func>
<name>info(Module) -> {ok,Info} | {error,Reason}</name>
<fsummary>Returns compiler information about the Module.</fsummary>
<type>
<v>Module = atom()</v>
<v>Info = list()</v>
<v>Reason = term()</v>
</type>
<desc>
<p>Returns the version of the <c>ASN.1</c> compiler that was
used to compile the module. It also returns the compiler options
that were used.</p>
<p>Use <c>Module:info()</c> instead of this function.</p>
</desc>
</func>
<func>
<name>utf8_binary_to_list(UTF8Binary) -> {ok,UnicodeList} | {error,Reason}</name>
<fsummary>Transforms an UTF8 encoded binary to a unicode list.</fsummary>
<type>
<v>UTF8Binary = binary()</v>
<v>UnicodeList = [integer()]</v>
<v>Reason = term()</v>
</type>
<desc>
<p>Transforms a UTF8 encoded binary
to a list of integers, where each integer represents one
character as its unicode value. The function fails if the binary
is not a properly encoded UTF8 string.</p>
<p>Use <seealso marker="stdlib:unicode#characters_to_list-1">unicode:characters_to_list/1</seealso> instead of this function.</p>
</desc>
</func>
<func>
<name>utf8_list_to_binary(UnicodeList) -> {ok,UTF8Binary} | {error,Reason}</name>
<fsummary>Transforms an unicode list to a UTF8 binary.</fsummary>
<type>
<v>UnicodeList = [integer()]</v>
<v>UTF8Binary = binary()</v>
<v>Reason = term()</v>
</type>
<desc>
<p>Transforms a list of integers,
where each integer represents one character as its unicode
value, to a UTF8 encoded binary.</p>
<p>Use <seealso marker="stdlib:unicode#characters_to_binary-1">unicode:characters_to_binary/1</seealso> instead of this function.</p>
