Struct slog_async::AsyncCore

[+] Show declaration

pub struct AsyncCore { /* fields omitted */ }

[−] Expand description

Core of Async drain

See Async for documentation.

Wrapping AsyncCore allows implementing custom overflow (and other errors) handling strategy.

Note: On drop AsyncCore waits for it’s worker-thread to finish (after handling all previous Records sent to it). If you can’t tolerate the delay, make sure you drop it eg. in another thread.
