Trait flexi_logger::writers::LogWriter

pub trait LogWriter: Sync + Send {
    fn write(&self, now: &mut DeferredNow, record: &Record) -> Result<()>;
    fn flush(&self) -> Result<()>;
    fn max_log_level(&self) -> LevelFilter;

    fn format(&mut self, format: FormatFunction) { ... }
    fn shutdown(&self) { ... }
}

Writes to a single log output stream.

Boxed instances of LogWriter can be used as additional log targets (see module description for more details).

Required methods

fn write(&self, now: &mut DeferredNow, record: &Record) -> Result<()>

Writes out a log line.

Errors

std::io::Error

fn flush(&self) -> Result<()>

Flushes any buffered records.

Errors

std::io::Error

fn max_log_level(&self) -> LevelFilter

Provides the maximum log level that is to be written.

Provided methods

fn format(&mut self, format: FormatFunction)

The default implementation is a no-op.

fn shutdown(&self)

Cleanup open resources, if necessary.
