Struct slog_stdlog::StdLog
source · [−]pub struct StdLog;
Expand description
Drain logging Record
s into log
crate
Any Record
passing through this Drain
will be forwarded
to log
crate, just like it was created with log
crate macros
in the first place. The message and key-value pairs will be formated
to be one string.
Caution needs to be taken to prevent circular loop where Logger
installed via slog-stdlog::set_logger
would log things to a StdLog
drain, which would again log things to the global Logger
and so on
leading to an infinite recursion.
