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

    pub struct RangeToInclusive<Idx> {
        pub end: Idx,
    }

🔬 This is a nightly-only experimental API. (`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

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
