Function systemd_journal_logger::init [−][src]
pub fn init() -> Result<(), SetLoggerError>
Expand description
Initialize journal logging.
Set LOG
as logger with log::set_logger
.
This function can only be called once during the lifetime of a program.
Default level
This function does not configure any default level for
log
; you need to configure the maximum level explicitly with
log::set_max_level
, as log
normally defaults to
log::LevelFilter::Off
which disables all logging.
Errors
This function returns an error if any logger was previously registered.
