Trait sherr::Log[−][src]

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

A trait encapsulating the operations required of a logger.

Required methods

`pub fn enabled(&self, metadata: &Metadata<'_>) -> bool`[src]

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.

`pub fn log(&self, record: &Record<'_>)`[src]

Logs the Record.

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

`pub fn flush(&self)`[src]

Flushes any buffered records.
