Struct std::ops::RangeToInclusive [] [src]

pub struct RangeToInclusive<Idx> {
    pub end: Idx,
}
Unstable (inclusive_range #28237)

: recently added, follows RFC

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
