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.
