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

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

An 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];
    assert_eq!(arr[ ..=2], [0,1,2  ]);
    assert_eq!(arr[1..=2], [  1,2  ]);  // RangeInclusiveRun

`pub const fn new(start: Idx, end: Idx) -> RangeInclusive<Idx>`

1.27.0

`pub 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 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

####

`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

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

[src]

🔬 This is a nightly-only experimental API. (`range_contains` #32311)

recently added as per RFC

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

# Examples

    #![feature(range_contains)]

    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));

`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

## 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`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
