[−][src]Crate pretty_env_logger
A logger configured via an environment variable which writes to standard error with nice colored output for log levels.
Example
extern crate pretty_env_logger; #[macro_use] extern crate log; fn main() { pretty_env_logger::init(); trace!("a trace example"); debug!("deboogging"); info!("such information"); warn!("o_O"); error!("boom"); }
Run the program with the environment variable RUST_LOG=trace
.
Defaults
The defaults can be setup by calling init()
or try_init()
at the start
of the program.
Enable logging
This crate uses env_logger internally, so the same ways of enabling logs through an environment variable are supported.
