Expand description

RangeBounds is implemented by Rust’s built-in range types, produced by range syntax like .., a.., ..b, ..=c, d..e, or f..=g.

Required methods

fn start_bound(&self) -> Bound<&T>[src]

Start index bound.

Returns the start value as a Bound.

Examples

use std::ops::Bound::*;
use std::ops::RangeBounds;

assert_eq!((..10).start_bound(), Unbounded);
assert_eq!((3..10).start_bound(), Included(&3));

fn end_bound(&self) -> Bound<&T>[src]

End index bound.

Returns the end value as a Bound.

Examples

use std::ops::Bound::*;
use std::ops::RangeBounds;

assert_eq!((3..).end_bound(), Unbounded);
assert_eq!((3..10).end_bound(), Excluded(&10));

Provided methods

fn contains<U>(&self, item: &U) -> bool where
    T: PartialOrd<U>,
    U: PartialOrd<T> + ?Sized, 1.35.0[src]

Returns true if item is contained in the range.

Examples

assert!( (3..5).contains(&4));
assert!(!(3..5).contains(&2));

assert!( (0.0..1.0).contains(&0.5));
assert!(!(0.0..1.0).contains(&f32::NAN));
assert!(!(0.0..f32::NAN).contains(&0.5));
assert!(!(f32::NAN..1.0).contains(&0.5));
