Crate logforth 

Logforth is a flexible logging framework for Rust applications, providing easy log dispatching and configuration.

Overview

Logforth allows you to set up multiple log dispatches with different filters and appenders. You can configure global log levels, use built-in appenders for stdout, stderr, files, or create custom appenders.

It provides out-of-the-box integrations with the log crate:

cargo add log
cargo add logforth -F starter-log

Examples

Simple setup with default stdout appender:

logforth::starter_log::stdout().apply();

log::info!("This is an info message.");

Advanced setup with custom filters and multiple appenders:

use logforth::append;
use logforth::record::LevelFilter;

logforth::starter_log::builder()
    .dispatch(|d| {
        d.filter(LevelFilter::Error)
            .append(append::Stderr::default())
    })
    .dispatch(|d| {
        d.filter(LevelFilter::Info)
            .append(append::Stdout::default())
    })
    .apply();

log::error!("Error message.");
log::info!("Info message.");
