A trait for sinks.

Required Methods

source

fn log(&self, record: &Record<'_>) -> Result<()>

Logs a record.

Implementors should always call Sink::should_log internally to filter records.

source

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

Flushes any buffered records.

source

fn level_filter(&self) -> LevelFilter

Gets the log level filter.

source

fn set_level_filter(&self, level_filter: LevelFilter)

Sets the log level filter.

source

fn set_formatter(&self, formatter: Box<dyn Formatter>)

Sets the formatter.

source

fn set_error_handler(&self, handler: Option<ErrorHandler>)

Sets a error handler.

Any errors that occur in Sink will be returned as directly as possible (e.g. returned to Logger), but some errors that are not likely to be returned directly will call this error handler. Most of these errors are uncommon.

If no handler is set, errors will be print to stderr and then ignored.
