Trait flexi_logger::filter::LogLineFilter

pub trait LogLineFilter {
    fn write(
        &self, 
        now: &mut DeferredNow, 
        record: &Record<'_>, 
        log_line_writer: &dyn LogLineWriter
    ) -> Result<()>;
}

Trait of the filter object.

Required methods

fn write(
    &self,
    now: &mut DeferredNow,
    record: &Record<'_>,
    log_line_writer: &dyn LogLineWriter
) -> Result<()>

Each log line that flexi_logger would write to the configured output channel is sent to this method.

Note that the log line only appears in the configured output channel if the filter implementation forwards it to the provided LogLineWriter.

Errors

If writing to the configured output channel fails.
