Bytefmt is Rust utility to parse byte string into bytes count and vice versa.

Installation

[dependencies]
bytefmt = "0.1.3"

Usage Examples

extern crate bytefmt;

use bytefmt;

fn main() {
    let input = "1.23 MB";

    // Parse string into bytes
    let bytes: u64 = bytefmt::parse(input).unwrap();
    assert_eq!(bytes, 1_230_000);

    // Format bytes into string
    let bytes_str = bytefmt::format(bytes);
    assert_eq!(&bytes_str, input);

    // Parse to specific unit
    let kb: f64 = bytefmt::parse_to(input, bytefmt::Unit::KB).unwrap();
    assert_eq!(kb, 1_230 as f64);

    // Format to specific unit
    let kb_str = bytefmt::format_to(bytes, bytefmt::Unit::KB);
    assert_eq!(&kb_str, "1230 KB");
}
