Struct mag::Area

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

A measurement of physical area.

Area is a derived quantity with a specific unit squared.

Operations

• Area + Area => Area
• Area - Area => Area
• Area * f64 => Area
• Area * Length => Volume
• Area / f64 => Area
• Area / Length => Length

Example

use mag::length::m;

let a = 150.0 * m * m; // Area<m>
let b = (10.0 * m) * (15.0 * m); // Area<m>

assert_eq!(a, b);
assert_eq!(a.to_string(), "150 m²");
assert_eq!(a / (5.0 * m), 30.0 * m);

Fields

quantity: f64

Area quantity
