Trait geng_core::prelude::log::Log

pub trait Log: Send + Sync {
    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 if a log message with the specified metadata would be logged.

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

fn log(&self, record: &Record)

Logs the 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.
