duration-string

duration-string is a library to convert from String to Duration and vice-versa.

Takes a String such as 100ms, 2s, 5m 30s, 1h10m and converts it into a Duration.

Takes a Duration and converts it into String.

The String format is a multiply of [0-9]+(ns|us|ms|[smhdwy])

Example

String to Duration:

use std::convert::TryFrom;
use duration_string::DurationString;
use std::time::Duration;

let d: Duration = DurationString::try_from(String::from("100ms")).unwrap().into();
assert_eq!(d, Duration::from_millis(100));

// Alternatively
let d: Duration = "100ms".parse::<DurationString>().unwrap().into();
assert_eq!(d, Duration::from_millis(100));

Duration to String:

use std::convert::TryFrom;
use duration_string::*;
use std::time::Duration;

let d: String = DurationString::from(Duration::from_millis(100)).into();
assert_eq!(d, String::from("100ms"));

Serde support

You can enable serialization/deserialization support by adding the feature serde

• Add serde feature

  duration-string = { version = "0.4.0", features = ["serde"] }
  

• Add derive to struct

  use duration_string::DurationString;
  use serde::{Deserialize, Serialize};
  
  #[derive(Serialize, Deserialize)]
  struct Foo {
    duration: DurationString
  }
