Struct Interval 

pub struct Interval<S: Scalar> {
    pub lower: S,
    pub upper: S,
}

Interval arithmetic for bounds propagation.

Represents an interval [lower, upper].

Fields

lower: S

Lower bound

upper: S

Upper bound

Implementations

impl<S: Scalar> Interval<S>

pub fn new(lower: S, upper: S) -> Self

Create a new interval.

pub fn point(x: S) -> Self

Create a point interval [x, x].

pub fn from_center(center: S, half_width: S) -> Self

Create from center and half-width.

pub fn width(&self) -> S

Width of the interval.

pub fn center(&self) -> S

Center of the interval.

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

Check if interval contains a value.

pub fn add(&self, other: &Self) -> Self

Add two intervals.

pub fn sub(&self, other: &Self) -> Self

Subtract two intervals.

pub fn mul(&self, other: &Self) -> Self

Multiply two intervals.

pub fn scale(&self, a: S) -> Self

Scale by a constant.

pub fn union(&self, other: &Self) -> Self

Union of two intervals.

pub fn intersection(&self, other: &Self) -> Option<Self>

Intersection of two intervals (None if empty).

Trait Implementations

impl<S: Clone + Scalar> Clone for Interval<S>

fn clone(&self) -> Interval<S>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S: Debug + Scalar> Debug for Interval<S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S: PartialEq + Scalar> PartialEq for Interval<S>

fn eq(&self, other: &Interval<S>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
