Function rustwide::logging::capture

pub fn capture<R>(storage: &LogStorage, f: impl FnOnce() -> R) -> R

Capture all log messages emitted inside a closure.

This function will capture all the message the provided closure emitted in the current thread, forwarding them to the provided LogStorage. rustwide’s logging system needs to be initialized before calling this function (either with init or init_with).

Example

use log::{info, debug, LevelFilter};
use rustwide::logging::{self, LogStorage};

let storage = LogStorage::new(LevelFilter::Info);
logging::capture(&storage, || {
    info!("foo");
    debug!("bar");
});

assert_eq!("[INFO] foo\n", storage.to_string());
