Struct ClosedInterval 

pub struct ClosedInterval {
    pub lo: f64,
    pub hi: f64,
}

Closed real interval [lo, hi].

Search callbacks may use infinite endpoints for conservative bounds, but neither endpoint may be NaN and lo <= hi must hold. The search validates every enclosure returned by a callback.

Fields

lo: f64

hi: f64

Implementations

impl ClosedInterval

pub const fn new(lo: f64, hi: f64) -> Self

pub const fn entire() -> Self

pub fn contains(self, value: f64) -> bool

pub fn contains_zero(self) -> bool

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

Directed outer enclosure of the exact sum of two intervals.

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