Struct std::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
The ...{integer}
syntax is a RangeToInclusive
:
#![feature(inclusive_range,inclusive_range_syntax)] assert_eq!((...5), std::ops::RangeToInclusive{ end: 5 });Run
It does not have an IntoIterator
implementation, so you can't use it in a
for
loop directly. This won't compile:
for i in ...5 { // ... }Run
When used as a slicing index, RangeToInclusive
produces a slice of all
array elements up to and including the index indicated by end
.
#![feature(inclusive_range_syntax)] let arr = [0, 1, 2, 3]; assert_eq!(arr[ ...2], [0,1,2 ]); // RangeToInclusive assert_eq!(arr[1...2], [ 1,2 ]);Run
Fields
end: Idx
The upper bound of the range (inclusive)
