+%% With an options list, maps an id whose optional value is the name

+%% session id has been returned from diameter:session_id/1; otherwise
+%% to a node that has called diameter_dist:attach/1 using the
+%% consistent hashing provided by hash/3, or to the local node() if a
+%% session id could not be extracted or there are no attached nodes. A
+%% handler process is spawned on the selected node using
+%% erlang:spawn_opt/4.
+%%
+%% Different behaviour can be configured by supplying an options map
+%% of the following form:
+%%
+%% #{search => non_neg_integer(),
+%% id => [binary()],
+%% default => discard | local | mfa(),
+%% dispatch => list() | mfa()}
+%%
+%% The search member limits the number of AVPs that are examined in
+%% the message (from the front), to avoid searching entire message in
+%% case it's known that peers follow RFC 6733's recommendation that
+%% Session-Id be placed at the head of a message. The default is to
+%% search the entire message.
+%%
+%% The id member restricts the optional value mapping to session ids
+%% whose DiamterIdentity is one of those specified. Set this to the
+%% list of Diameter identities advertised by the service in question
+%% (typically one) to ensure that only locally generated session ids
+%% are mapped; or to the empty list to disable the mapping.
+%%
+%% The default member determines where to handle a message whose
+%% Session-Id isn't found or whose optional value isn't mapped to the
+%% name of a connected node. The atom local says the local node, an
+%% MFA is invoked on Session-Id | false, the name of the diameter
+%% service, and the message binary, and should return either a node()
+%% or false to discard the message. Defaults to {diameter_dist, hash, []}.
+%%
+%% The dispatch member determines how the pid() of the request handler
+%% process is retrieved. An MFA is applied to a previously selected
+%% node(), and the module, function, and arguments list to apply in
+%% the handler process to handle the request, the MFA being supplied
+%% by diameter, and returns pid() | discard. A list is equivalent to
+%% {erlang, spawn_opt, []}. Defaults to [].
+%%
+%% This can be used with search = 0 to route on something other than
+%% Session-Id, but this is probably no simpler than just implementing
+%% an own spawn_opt callback. (Except with the default dispatch possibly.)
+%%
+%% Note that if the peer is also implemented with OTP diameter and
+%% generating session ids with diameter:session_id/1 then
+%% route_session/2 can map an optional value to a local node that
+%% happens to have the same name as one of the peer's nodes. This
+%% could lead to an uneven distribution; for example, if the peer
+%% nodes are a subset of the local nodes. In practice, it's typically
+%% known if it's peers or the local node originating sessions; if the
+%% former then setting id = [] disables the optional value mapping, if
