Struct core::ops::RangeToInclusive
[−]
[src]
pub struct RangeToInclusive<Idx> { pub end: Idx, }
An inclusive range which is only bounded above: { x | x <= end }.
Use ...end
(three dots) for its shorthand.
See the contains()
method for its characterization.
It cannot serve as an iterator because it doesn't have a starting point.
Examples
#![feature(inclusive_range,inclusive_range_syntax)] fn main() { assert_eq!((...5), std::ops::RangeToInclusive{ end: 5 }); let arr = [0, 1, 2, 3]; assert_eq!(arr[ ...2], [0,1,2 ]); // RangeToInclusive assert_eq!(arr[1...2], [ 1,2 ]); }#![feature(inclusive_range,inclusive_range_syntax)] fn main() { assert_eq!((...5), std::ops::RangeToInclusive{ end: 5 }); let arr = [0, 1, 2, 3]; assert_eq!(arr[ ...2], [0,1,2 ]); // RangeToInclusive assert_eq!(arr[1...2], [ 1,2 ]); }
Fields
end | The upper bound of the range (inclusive) |
