Struct core::range::RangeInclusive
source · pub struct RangeInclusive<Idx> {
pub start: Idx,
pub end: Idx,
}
🔬This is a nightly-only experimental API. (
new_range_api
#125687)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
:
Fields§

🔬This is a nightly-only experimental API. (
new_range_api
#125687)The lower bound of the range (inclusive).
end: Idx
🔬This is a nightly-only experimental API. (
new_range_api
#125687)The upper bound of the range (inclusive).

sourcepub fn is_empty(&self) -> bool
🔬This is a nightly-only experimental API. (new_range_api
#125687)
pub fn is_empty(&self) -> bool
new_range_api
#125687)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:
