Trait witchcraft_log::Log

pub trait Log: Sync + Send {
    fn enabled(&self, metadata: &Metadata) -> bool;
    fn log(&self, record: &Record);
    fn flush(&self);
}

A trait encapsulating the operations required of a logger.

Required methods

fn enabled(&self, metadata: &Metadata) -> bool

Determines ifa log message with the specified metadata would be logged.

This is used by the enabled! macro to allow callers to avoid expensive computation of log message parameters if the message would be discarded anyway.

fn log(&self, record: &Record)

Logs a Record.

Note that enabled is not necessarily called before this method. Implementations of log should perform all necessary filtering internally.

fn flush(&self)

Flushes any buffered records.
