humanize-rs
This lib aims at converting human-readable strings to specific types. It's mainly used in parsing config files.
Bytes
use humanize_rs::bytes::{Bytes, Unit};
let gigabytes1 = Bytes::new(1, Unit::GiByte);
let gigabytes2 = "1 GiB".parse::<Bytes>();
assert_eq!(gigabytes1, gigabytes2);
Duration
use humanize_rs::duration::parse;
use std::time::Duration;
assert_eq!(parse("1h 30m 71s"), Ok(Duration::from_secs(60 * 90 + 71)));
