[−][src]Crate fts_gamemath
fts_gamemath is a collection of Rust crates that provide basic building blocks for 3d video game math
fts_units
fts_units is a Rust library that enables compile-time type-safe mathematical operations using units of measurement.
use fts_units::si_system::quantities::f32::*;
let d = Meters::new(10.0);
let t = Seconds::new(2.0);
let v = d / v; // units will be m·s⁻¹
let err = d + t; // compile error
This easily extends into complex operations.
use fts_units::si_system::quantities::*; fn calc_ballistic_range(speed: MetersPerSecond<f32>, gravity: MetersPerSecond2<f32>, initial_height: Meters<f32>) -> Meters<f32> { let d2r = 0.01745329252; let angle : f32 = 45.0 * d2r; let cos = Dimensionless::<f32>::new(angle.cos()); let sin = Dimensionless::<f32>::new(angle.sin()); let range = (speed*cos/gravity) * (speed*sin + (speed*speed*sin*sin + Dimensionless::<f32>::new(2.0)*gravity*initial_height).sqrt()); range }
You can convert between units and cast between types.
let m = Meters::<f32>::new(7.73); let km : Kilometers<f32> = m.convert_into(); assert_eq!(km.amount(), 0.00773); let i : Meters<i32> = m.cast_into(); assert_eq!(i.amount(), 7);
For additional features and examples refer to the fts_units documentation.
