Logger that aims to provide a simple case of env_logger that just logs to stderr based on verbosity.

For a working example for StructOpt, clap, and docopt please see the crate level documentation.

For example binaries showing how module level logging works, please see the large-example crate in examples/.

• stderrlog 0.6.x supports
  1. Rust 1.48.0 and newer
  2. log >= 0.4.11
• stderrlog 0.5.x supports
  1. Rust 1.36.0 and newer
  2. log >= 0.4.11
• stderrlog 0.4.x supports

  2. log 0.3.x
• stderrlog 0.2.x supports
  1. Rust 1.13.0 and newer
  2. log >= 0.3.0, < 0.3.9

Add this to your Cargo.toml:

[dependencies]
stderrlog = "0.4"

and this to your main():

stderrlog::new().verbosity(args.flag_v).quiet(args.flag_q).init().unwrap();

where your args struct is defined as:

struct Args {
    flag_v: usize,
    flag_q: bool,
    ...
}
