1.28.0[][src]Trait std::ops::RangeBounds

pub trait RangeBounds<T> where
    T: ?Sized
{ fn start_bound(&self) -> Bound<&T>;
fn end_bound(&self) -> Bound<&T>; fn contains<U>(&self, item: &U) -> bool
    where
        T: PartialOrd<U>,
        U: PartialOrd<T> + ?Sized
, { ... } }

RangeBounds is implemented by Rust's built-in range types, produced by range syntax like .., a.., ..b or c..d.

Required methods

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));Run

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));Run

Provided methods

🔬 This is a nightly-only experimental API. (range_contains #32311)

recently added as per RFC

Returns true if item is contained in the range.

Examples

#![feature(range_contains)]

use std::f32;

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));Run
