Trait Lerp
Source pub trait Lerp {
// Required methods
fn lerp(self, end: Self, percent: f32) -> Self;
fn inv_lerp(self, end: Self, point: Self) -> f32;
}
calculate the point at percent between self and end
§Usage
assert_eq!(10.lerp(20, 0.5), 15);
assert_eq!(10.lerp(20, 0.1), 11);
internally the values are cast as f32 and rounded before being returned
calculate the percent for point between self and end
§Usage
assert_eq!(10.inv_lerp(20, 15), 0.5);
assert_eq!(10.inv_lerp(20, 11), 0.1);
internally the values are cast as f32 and rounded before being returned
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
