Struct ringlog::RingLog

pub struct RingLog { /* private fields */ }

A type which implements an asynchronous logging backend.

Implementations

impl RingLog

pub fn start(self) -> Box<dyn Drain>

Register the logger and return a type which implements Drain. It is up to the user to periodically call flush on the resulting drain.
