• Documentation on Docs.rs

Usage

use simple_logger::SimpleLogger;

fn main() {
    SimpleLogger::new().init().unwrap();

    log::warn!("This is an example message.");
}

This outputs:

2015-02-24 01:05:20 WARN [logging_example] This is an example message.

You can run the above example with:

cargo run --example init

Coloured output and timestamps will be enabled by default. You can remove these features and their respective dependencies by disabling all features in your Cargo.toml.

[dependencies.simple_logger]
default-features = false

To include the timestamps feature, but not the colors feature:

[dependencies.simple_logger]
default-features = false
features = ["timestamps"]

To include the colors feature, but not the timestamps feature:

[dependencies.simple_logger]
default-features = false
features = ["colors"]

To direct logging output to stderr use the stderr feature:

[dependencies.simple_logger]
features = ["stderr"]

This can be combined with any other feature.

simple_logger is licenced under the MIT Licence.
