Represents a sink

Required Methods§

Source

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

Logs a record.

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.

Most errors that occur in Sink will be returned as directly as possible (e.g. returned to Logger), but some errors that cannot be returned immediately, this function will be called. For example, asynchronous errors.

If no handler is set, default error handler will be used.
