Struct Speed

pub struct Speed<L, P>
where
    L: Unit,
    P: Unit,
{
    pub quantity: f64,
    /* private fields */
}

Quantity of speed.

Speed is a derived quantity with length units and time units.

Operations

• Length * Frequency => Speed
• Length / time unit => Speed
• Length / Period => Speed
• Speed + Speed => Speed
• Speed - Speed => Speed
• Speed * f64 => Speed
• f64 * Speed => Speed
• i32 * Speed => Speed
• Speed / f64 => Speed

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

Example

use mag::{Speed, length::{m, mi}, time::{h, s}};

let a = 7.4 * m / s;
let b = 55 * mi / h;

assert_eq!(a.to_string(), "7.4 m/s");
assert_eq!(b.to_string(), "55 mi/h");

Fields
