Enum collections::Bound

pub enum Bound<T> {
    Included(T),
    Excluded(T),
    Unbounded,
}

An endpoint of a range of keys.

Examples

Bounds are range endpoints:

use std::ops::RangeArgument;
use std::ops::Bound::*;

assert_eq!((..100).start(), Unbounded);
assert_eq!((1..12).start(), Included(&1));
assert_eq!((1..12).end(), Excluded(&12));

Variants

Included(T)

An inclusive bound.

Excluded(T)

An exclusive bound.

Unbounded

An infinite endpoint. Indicates that there is no bound in this direction.
