Expand description

Adds functionalities to the Duration type.

Required Methods

source

fn as_duration(&self) -> &Duration

Retrieves the duration from Self.

Provided Methods

source

fn to_chrono_duration(&self) -> Duration

Retrieves the chrono duration from Self.

source

fn from_micros(ts: u64) -> Self

Creates a duration from a timestamp in microseconds.

source

fn parse_secs<Str>(ts: &Str) -> Result<Self, Error> where
Str: AsRef<str> + ?Sized,

Duration parser from an amount of seconds, seen as a float.

Examples

use base::prelude::time::{Duration, DurationExt};
let s_list = vec![
    ("320.74", Duration::new(320, 740_000_000)),
    ("703470.0074", Duration::new(703470, 7_400_000)),
    ("0.2", Duration::new(0, 200_000_000)),
    ("7.0", Duration::new(7, 0)),
    (".003", Duration::new(0, 3_000_000)),
    ("42", Duration::new(42, 0)),
];
for (s, exp) in s_list {
    let duration = Duration::parse_secs(s).unwrap();
    assert_eq! { duration, exp }
}
