pub struct RangeInclusive<Idx> {
pub start: Idx,
pub end: Idx,
}
🔬This is a nightly-only experimental API. (
new_range_api
)Expand description
A range bounded inclusively below and above (start..=end
).
The RangeInclusive
start..=end
contains all values with x >= start
and x <= end
. It is empty unless start <= end
.
§Examples
The start..=end
syntax is a RangeInclusive
:
#![feature(new_range_api)]
use core::range::RangeInclusive;
assert_eq!(RangeInclusive::from(3..=5), RangeInclusive { start: 3, end: 5 });
assert_eq!(3 + 4 + 5, RangeInclusive::from(3..=5).into_iter().sum());
Fields§
§start: Idx
🔬This is a nightly-only experimental API. (
new_range_api
)The lower bound of the range (inclusive).
end: Idx
🔬This is a nightly-only experimental API. (
new_range_api
)The upper bound of the range (inclusive).

sourcepub fn contains<U>(&self, item: &U) -> bool
🔬This is a nightly-only experimental API. (new_range_api
)
pub fn contains<U>(&self, item: &U) -> bool
new_range_api
)Returns true
if item
is contained in the range.
§Examples
#![feature(new_range_api)]
use core::range::RangeInclusive;
assert!(!RangeInclusive::from(3..=5).contains(&2));
assert!( RangeInclusive::from(3..=5).contains(&3));
assert!( RangeInclusive::from(3..=5).contains(&4));
assert!( RangeInclusive::from(3..=5).contains(&5));
assert!(!RangeInclusive::from(3..=5).contains(&6));
assert!( RangeInclusive::from(3..=3).contains(&3));
assert!(!RangeInclusive::from(3..=2).contains(&3));
assert!( RangeInclusive::from(0.0..=1.0).contains(&1.0));
assert!(!RangeInclusive::from(0.0..=1.0).contains(&f32::NAN));
assert!(!RangeInclusive::from(0.0..=f32::NAN).contains(&0.0));
assert!(!RangeInclusive::from(f32::NAN..=1.0).contains(&1.0));
sourcepub fn is_empty(&self) -> bool
🔬This is a nightly-only experimental API. (new_range_api
)
pub fn is_empty(&self) -> bool
new_range_api
)Returns true
if the range contains no items.
§Examples
#![feature(new_range_api)]
use core::range::RangeInclusive;
assert!(!RangeInclusive::from(3..=5).is_empty());
assert!(!RangeInclusive::from(3..=3).is_empty());
assert!( RangeInclusive::from(3..=2).is_empty());
The range is empty if either side is incomparable:
#![feature(new_range_api)]
use core::range::RangeInclusive;
assert!(!RangeInclusive::from(3.0..=5.0).is_empty());
assert!( RangeInclusive::from(3.0..=f32::NAN).is_empty());
assert!( RangeInclusive::from(f32::NAN..=5.0).is_empty());

pub fn iter(&self) -> IterRangeInclusive<Idx> ⓘ
new_range_api
)Creates an iterator over the elements within this range.
Shorthand for .clone().into_iter()
§Examples
#![feature(new_range_api)]
use core::range::RangeInclusive;
let mut i = RangeInclusive::from(3..=8).iter().map(|n| n*n);
