A convenience macro for logging at the info log level.

Examples

#![feature(rustc_private)] #[macro_use] extern crate log; fn main() { let ret = 3; info!("this function is about to return: {}", ret); }

#[macro_use] extern crate log;

fn main() {
    let ret = 3;
    info!("this function is about to return: {}", ret);
