Struct AsyncLogger

pub struct AsyncLogger { /* private fields */ }

Asynchronous logger

The very first time a message is logged on a channel in a thread, a copy of the sending end of the channel is made, requiring a single mutex lock and clone. For further calls, this sending end is cached as a thread local.

Panics

Logging may panic in the unlikely event the lock becomes poisoned upon logging from a new thread.

pub fn new(bufsize: usize) -> (AsyncLogger, Receiver<LogMessage>)
