# 1.26.0[−][src]Struct std::ops::RangeInclusive

    pub struct RangeInclusive<Idx> { /* fields omitted */ }

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`.

This iterator is fused, but the specific values of `start` and `end` after iteration has finished are unspecified other than that `.is_empty()` will return `true` once no more values will be produced.

# Examples

    assert_eq!((3..=5), std::ops::RangeInclusive::new(3, 5));
    assert_eq!(3 + 4 + 5, (3..=5).sum());

    let arr = [0, 1, 2, 3, 4];
    assert_eq!(arr[ ..  ], [0,1,2,3,4]);
    assert_eq!(arr[ .. 3], [0,1,2    ]);
    assert_eq!(arr[ ..=3], [0,1,2,3  ]);
    assert_eq!(arr[1..  ], [  1,2,3,4]);
    assert_eq!(arr[1.. 3], [  1,2    ]);
    assert_eq!(arr[1..=3], [  1,2,3  ]);  // RangeInclusive

## Methods

### `impl<Idx> RangeInclusive<Idx>`[src]

#### `pub const fn new(start: Idx, end: Idx) -> RangeInclusive<Idx>`1.27.0[src]

Creates a new inclusive range. Equivalent to writing `start..=end`.

# Examples

    use std::ops::RangeInclusive;

    assert_eq!(3..=5, RangeInclusive::new(3, 5));

Run

#### `pub const fn start(&self) -> &Idx` 1.27.0[src]

Returns the lower bound of the range (inclusive).

When using an inclusive range for iteration, the values of `start()` and `end()` are unspecified after the iteration ended. To determine whether the inclusive range is empty, use the `is_empty()` method instead of comparing `start() > end()`.

Note: the value returned by this method is unspecified after the range has been iterated to exhaustion.

# Examples

    assert_eq!((3..=5).start(), &3);

Run

#### `pub const fn end(&self) -> &Idx` 1.27.0[src]

Returns the upper bound of the range (inclusive).

When using an inclusive range for iteration, the values of `start()` and `end()` are unspecified after the iteration ended. To determine whether the inclusive range is empty, use the `is_empty()` method instead of comparing `start() > end()`.

Note: the value returned by this method is unspecified after the range has been iterated to exhaustion.

# Examples

    assert_eq!((3..=5).end(), &5);

Run

#### `pub fn into_inner(self) -> (Idx, Idx)`1.27.0[src]

Destructures the `RangeInclusive` into (lower bound, upper (inclusive) bound).

Note: the value returned by this method is unspecified after the range has been iterated to exhaustion.

# Examples

    assert_eq!((3..=5).into_inner(), (3, 5));

Run

### `impl<Idx> RangeInclusive<Idx> where
Idx: PartialOrd<Idx>,` [src]

#### `pub fn contains<U>(&self, item: &U) -> bool where
Idx: PartialOrd<U>,
U: PartialOrd<Idx> + ?Sized,` 1.35.0[src]

Returns `true` if `item` is contained in the range.

# Examples

    use std::f32;

    assert!(!(3..=5).contains(&2));
    assert!( (3..=5).contains(&3));
    assert!( (3..=5).contains(&4));
    assert!( (3..=5).contains(&5));
    assert!(!(3..=5).contains(&6));

    assert!( (3..=3).contains(&3));
    assert!(!(3..=2).contains(&3));

    assert!( (0.0..=1.0).contains(&1.0));
    assert!(!(0.0..=1.0).contains(&f32::NAN));
    assert!(!(0.0..=f32::NAN).contains(&0.0));
    assert!(!(f32::NAN..=1.0).contains(&1.0));

Run

#### `pub fn is_empty(&self) -> bool`[src]

🔬 This is a nightly-only experimental API. (`range_is_empty` #48111)

recently added

Returns `true` if the range contains no items.

# Examples

    #![feature(range_is_empty)]

    assert!(!(3..=5).is_empty());
    assert!(!(3..=3).is_empty());
    assert!( (3..=2).is_empty());

Run

The range is empty if either side is incomparable:

    #![feature(range_is_empty)]

    use std::f32::NAN;
    assert!(!(3.0..=5.0).is_empty());
    assert!( (3.0..=NAN).is_empty());
    assert!( (NAN..=5.0).is_empty());

Run

This method returns `true` after iteration has finished:

    #![feature(range_is_empty)]

    let mut r = 3..=5;
    for _ in r.by_ref() {}
    // Precise field values are unspecified here
    assert!(r.is_empty());

Run

### `impl SliceIndex<str> for RangeInclusive<usize>`[src]

Implements substring slicing with syntax `&self[begin ..= end]` or `&mut self[begin ..= end]`.

Returns a slice of the given string from the byte range [`begin`, `end`]. Equivalent to `&self [begin .. end + 1]` or `&mut self[begin .. end + 1]`, except if `end` has the maximum value for `usize`.

This operation is `O(1)`.

# Panics

Panics if `begin` does not point to the starting byte offset of a character (as defined by `is_char_boundary`), if `end` does not point to the ending byte offset of a character (`end + 1` is either a starting byte offset or equal to `len`), if `begin > end`, or if `end >= len`.
