Struct mag::Period

pub struct Period<U> where
    U: Unit,  {
    pub quantity: f64,
    // some fields omitted
}

A measurement of period, duration or interval of time.

Period is a base quantity with a specific unit.

Operations

• Period + Period => Period
• Period - Period => Period
• Period * f64 => Period
• f64 * Period => Period
• f64 * unit => Period
• f64 / Period => Frequency

Units must be the same for operations with two Period operands. The to method can be used for conversion.

use mag::time::{min, s};

let a = 15.0 * min;
let b = 90.0 * s;

assert_eq!(a.to_string(), "15 min");
assert_eq!((a + b.to()).to_string(), "16.5 min");

Fields

quantity: f64

Period quantity
