MS converter library

Fast abstraction for converting human-like times into milliseconds. Like, are 1d to 86400000.

There are two ways to calculate milliseconds:

  • In the runtime crate::ms_converter::ms
  • In the compilation time crate::ms_converter::ms_expr

Getting Started


Add this to your Cargo.toml:

ms-converter = "1.0"


Running ms converter in Runtime:

use crate::ms_converter::ms;

let value = ms("1d").unwrap();
assert_eq!(value, 86400000)

Convert ms in the compilation step:

use crate::ms_converter::ms_expr;

const VALUE: i64 = ms_expr!(i64, 1 d);
assert_eq!(VALUE, 86400000)

Convert ms into time.Duration

use crate::ms_converter::ms_into_time;

let value = ms_into_time("1d").unwrap();
assert_eq!(value.as_millis(), 86400000)

Supported time strings

  • Years: years, year, yrs, yr, y
  • Weeks: weeks, week, w
  • Days: days, day, d
  • Hours: hours, hour, hrs, hr, h
  • Minutes: minutes, minute, mins, min, m
  • Seconds: seconds, second, secs, sec, s
  • Milliseconds: milliseconds, millisecond, msecs, msec, ms and empty postfix


You can check the performance diff between ms_converter and ms libraries here.

Also, the macro has no time in the runtime! It will be converted into the const value.
