log4rs

Documentation is available at https://sfackler.github.io/log4rs/doc/v0.3.3/log4rs

log4rs is a highly configurable logging framework modeled after Java's Logback and log4j libraries.

log.toml: ```toml

Scan this file for changes every 30 seconds

refresh_rate = 30

An appender named "stdout" that writes to stdout

[appender.stdout] kind = "console"

An appender named "requests" that writes to a file with a custom pattern

[appender.requests] kind = "file" path = "log/requests.log" pattern = "%d - %m"

Set the default logging level to "warn" and attach the "stdout" appender to the root

[root] level = "warn" appenders = ["stdout"]

Raise the maximum log level for events sent to the "app::backend::db" logger to "info"

[[logger]] name = "app::backend::db" level = "info"

Route log events sent to the "app::requests" logger to the "requests" appender,

and not the normal appenders installed at the root

[[logger]] name = "app::requests" level = "info" appenders = ["requests"] additive = false ```

lib.rs: ```rust

[macro_use]

extern crate log; extern crate log4rs;

use std::default::Default;

fn main() { log4rs::init_file("config/log.toml", Default::default()).unwrap();

info!("booting up");

...

} ```
