A Rust library to format std::time::Duration the same way Go does.
This is almost a verbatim copy of the algorithm Go uses.
Add to your Cargo.toml file:
[dependencies]
durationfmt = { git = "https://github.com/kdar/durationfmt-rs.git" }and this to your crate root:
extern crate durationfmt;extern crate durationfmt;
use std::time::Duration;
fn main() {
let d = Duration::new(0, 0);
println!("{}", durationfmt::to_string(d));
// 0s
let d = Duration::new(90, 0);
println!("{}", durationfmt::to_string(d));
// 1m30s
let d = Duration::new(209, 1_000);
println!("{}", durationfmt::to_string(d));
// 3m29.000001s
}
