Crate duration_string

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

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

Takes a duration and makes it into string.

The string format is multiples of [0-9]+(ns|us|ms|[smhdwy])

Example

String to duration

use duration_string::DurationString;
use std::time::Duration;
let d: Duration = DurationString::from_string(String::from("100ms")).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"));
// Alternatively:
let d: Duration = "100ms".parse::<DurationString>().unwrap().into();
assert_eq!(d, Duration::from_millis(100));

Serde support

You can enable serialize/unserialize support by adding the feature serde

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

use serde::{Deserialize, Serialize};
use serde_json;
use duration_string::DurationString;

#[derive(Serialize, Deserialize)]
struct SerdeSupport {
    t: DurationString,
}
let s = SerdeSupport {
    t: DurationString::from_string(String::from("1m")).unwrap(),
};
assert_eq!(r#"{"t":"1m"}"#, serde_json::to_string(&s).unwrap());
