youlog

A thin logging implementation for Rust's log facade.

This crate allows for providing custom functions to the logger.

Examples where this might be useful:

• Logging logic needs to be different across log levels
• Another application's logger is being used like with godot-rust
• An existing crate is too opinionated in how it handles logging

Example

use log::LevelFilter;
use youlog::Builder;

Builder::new()
    .global_level(LevelFilter::Info)
    .log_fn(LevelFilter::Info, |r| {
        println!("info {}", r.args().as_str().unwrap_or_default());
    })
    .init()
    .expect("unable to init logger");

log::info!("this is an info log!");

Status

Module level filters are still WIP, but those can just be implemented in a logging function anyways :)
