Struct Rangef

#[repr(C)]pub struct Rangef {
    pub min: f32,
    pub max: f32,
}

Expand description

§min: f32§max: f32

Implementations§

impl Rangef

pub const EVERYTHING: Rangef

Infinite range that contains everything, from -∞ to +∞, inclusive.

pub const NOTHING: Rangef

The inverse of Self::EVERYTHING: stretches from positive infinity to negative infinity. Contains nothing.

pub const NAN: Rangef

An invalid Rangef filled with f32::NAN.

pub fn new(min: f32, max: f32) -> Rangef

pub fn point(min_and_max: f32) -> Rangef

pub fn span(self) -> f32

The length of the range, i.e. max - min.

pub fn center(self) -> f32

The center of the range

pub fn contains(self, x: f32) -> bool

pub fn clamp(self, x: f32) -> f32

Equivalent to x.clamp(min, max)

pub fn as_positive(self) -> Rangef

Flip min and max if needed, so that min <= max after.

pub fn shrink(self, amnt: f32) -> Rangef

Shrink by this much on each side, keeping the center

pub fn expand(self, amnt: f32) -> Rangef

Expand by this much on each side, keeping the center

pub fn intersection(self, other: Rangef) -> Rangef

The overlap of two ranges, i.e. the range that is contained by both.

If the ranges do not overlap, returns a range with span() < 0.0.

assert_eq!(Rangef::new(0.0, 10.0).intersection(Rangef::new(5.0, 15.0)), Rangef::new(5.0, 10.0));
assert_eq!(Rangef::new(0.0, 10.0).intersection(Rangef::new(10.0, 20.0)), Rangef::new(10.0, 10.0));
assert!(Rangef::new(0.0, 10.0).intersection(Rangef::new(20.0, 30.0)).span() < 0.0);
