-spec channel_encode_opts(ChannelOpts :: partisan:channel_opts()) -> list().

Returns the erlang:term_to_iovec/2 options implied by a channel's compression option.

This is the single source of truth for the derivation. It is used both by partisan_peer_service_client when it caches the options for a connection, and by the dispatch path when it encodes a message in the *calling* process before handing it to that connection. Those two must agree: if the caller encodes with different options than the connection would have, the bytes on the wire change depending on which path a message took.

-spec encode(Term :: term(), Opts :: list()) -> erlang:ext_iovec() | iolist().

If pid_encoding or ref_encoding configuration options are enabled, this function will ignore Opts and return an iolist(). Otherwise, the function calls erlang:term_to_iovec(Term, Opts).'

-spec format_posix_error(Reason :: inet:posix() | system_limit) ->
                            Message :: binary() | (Reason :: inet:posix() | system_limit).

Given a POSIX error reason see inet and file, returns a descriptive binary string of the error in English and adding Reason at the end of the description inside parenthesis.
