Struct parallel_logger::ParallelLogger

pub struct ParallelLogger { /* private fields */ }

A log::Log implementation that executes all logging on a separate thread.

Simply pass the actual loggers in the call to ParallelLogger::init.

Implementations

impl ParallelLogger

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

Initializes the ParallelLogger.

This function sets up a new ParallelLogger with the specified log level and the actual loggers. It starts a new logging thread that listens for log messages on a channel. 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.
• actual_loggers - The actual loggers that the ParallelLogger will forward log messages to.

Panics

If another logger was already set for the log crate, or if no actual logger was provided, this function panics.
