Tiny interface to Journald socket
See man sd_journal_sendv, man systemd.journal-fields
abstract datatype: handle()
key() = iodata()
log_msg() = #{key() => value()} | [{key(), value()}]
value() = iodata() | integer() | atom()
| close/1 | Closes journald log socket. |
| format/1 | Formats a flat Key-Value message to a (non-documented) format acceptable by journald socket. |
| is_handle/1 | Returns true if the argument is handle() and false otherwise. |
| log/2 | Logs a Key - Value message to journald socket. |
| open/1 | Opens journald log socket. |
close(State::handle()) -> ok
Closes journald log socket
format(Map::log_msg()) -> iodata()
Formats a flat Key-Value message to a (non-documented) format acceptable by journald socket
is_handle(State::any()) -> boolean()
Returns true if the argument is handle() and false otherwise.
log(KV::log_msg(), State::handle()) -> ok | {error, inet:posix()}
Logs a Key - Value message to journald socket
Keys have to beiodata() and should not contain newlines or = signs.
Values can be iodata(), atom() or integer() and may contain any binaries. utf8 is
preferrable
open(Opts::#{socket_path => file:filename_all()}) -> handle()
Opens journald log socket
