Type Alias ErrorHandler 

pub type ErrorHandler = Arc<dyn Fn(&Error) + Send + Sync>;

Available on crate feature std only.

Callback invoked for every sink error, flush error, and message formatting error the logger encounters.

The handler runs on the thread that logged the record. If the handler itself logs through a logger whose sink keeps failing, the nested failures are not reported again (a per-thread guard prevents unbounded recursion), but the nested records are still dispatched.

Examples

use std::sync::Arc;
use log_io::{ErrorHandler, Logger};

let handler: ErrorHandler = Arc::new(|err| eprintln!("logging failed: {err}"));
let logger = Logger::builder().stderr_logfmt().on_error(handler).build();
