duration-string

duration-string is a string to duration and visa-versa lib.

Takes a string such as 100ms, 2s, 5m and converts it into a Duration Takes a duration and makes it into string.

The string format is [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 serialize/unserialize support by adding the feature serde_support

• Add serde_support to the dependency duration-string = { version = "0.0.1", features = ["serde_support"] }
• Add derive to struct

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