Struct Bounds 

pub struct Bounds<T> {
    pub lower: Option<T>,
    pub upper: Option<T>,
}

Per-variable box constraint.

Examples

let b = Bounds::both(0.0_f64, 1.0);
assert_eq!(b.lower, Some(0.0));
assert_eq!(b.upper, Some(1.0));

Fields

lower: Option<T>

Optional lower bound.

upper: Option<T>

Optional upper bound.

Implementations

impl<T> Bounds<T>

pub fn none() -> Self

No bounds.

Examples

let b = Bounds::<f64>::none();
assert!(b.lower.is_none());
assert!(b.upper.is_none());

pub fn lower(lb: T) -> Self

Lower bound only.

Examples

let b = Bounds::lower(0.0_f64);
assert_eq!(b.lower, Some(0.0));

pub fn upper(ub: T) -> Self

Upper bound only.

Examples

let b = Bounds::upper(10.0_f64);
assert_eq!(b.upper, Some(10.0));

pub fn both(lb: T, ub: T) -> Self

Both lower and upper bounds.

Examples

let b = Bounds::both(-1.0_f64, 1.0);
assert_eq!(b.lower, Some(-1.0));
assert_eq!(b.upper, Some(1.0));
