Function tracing_appender::rolling::daily
source · pub fn daily(
directory: impl AsRef<Path>,
file_name_prefix: impl AsRef<Path>
) -> RollingFileAppender ⓘ
Expand description
Creates a daily-rotating file appender.
The appender returned by rolling::daily
can be used with non_blocking
to create
a non-blocking, daily file appender.
A RollingFileAppender
has a fixed rotation whose frequency is
defined by Rotation
. The directory
and
file_name_prefix
arguments determine the location and file name’s prefix
of the log file. RollingFileAppender
automatically appends the current date in UTC.
Examples
fn main () {
let appender = tracing_appender::rolling::daily("/some/path", "rolling.log");
let (non_blocking_appender, _guard) = tracing_appender::non_blocking(appender);
let subscriber = tracing_subscriber::fmt().with_writer(non_blocking_appender);
tracing::subscriber::with_default(subscriber.finish(), || {
tracing::event!(tracing::Level::INFO, "Hello");
});
}
This will result in a log file located at /some/path/rolling.log.yyyy-MM-dd-HH
.
