Struct ParallelLogger 

pub struct ParallelLogger { /* private fields */ }

A log::Log implementation that executes all logging in parallel.
Simply pass the actual loggers in the call to ParallelLogger::init.

Implementations

impl ParallelLogger

pub fn init( log_level: LevelFilter, mode: ParallelMode, actual_loggers: Vec<Box<dyn Log>>, ) -> ShutdownHandle

Initializes the ParallelLogger.

This function sets up a new ParallelLogger with the specified log level, the parallel execution mode and the actual loggers. Depending on the ParallelMode setting, either one or more threads will be created to process the actual loggers. The ParallelLogger is then set as the global logger for the log crate.

Arguments

• log_level - The maximum log level that the logger will handle. Log messages with a level higher than this will be ignored. This will also apply to the actual loggers even though those might have a higher log level set in their configs.
• mode - The parallel execution mode that the ParallelLogger will use.
• actual_loggers - The actual loggers that the ParallelLogger will forward log messages to.

Returns

A ShutdownHandle that can be used to shut down the ParallelLogger and possibly flush the remaining messages in the queue.

Panics

• if another logger was already set for the log crate
• if no actual logger was provided
• if a thread could not be created
