[−][src]Struct slog_async::AsyncGuard
Async guard
All Drains are reference-counted by every Logger that uses them.
Async drain runs a worker thread and sends a termination (and flushing)
message only when being droped. Because of that it's actually
quite easy to have a left-over reference to a Async drain, when
terminating: especially on panics or similar unwinding event. Typically
it's caused be a leftover reference like Logger in thread-local variable,
global variable, or a thread that is not being joined on. It might be a
program bug, but logging should work reliably especially in case of bugs.
AsyncGuard is a remedy: it will send a flush and termination message to
a Async worker thread, and wait for it to finish on it's own drop. Using it
is a simplest way to guarantee log flushing when using slog_async.
