Struct std::ops::RangeInclusive

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

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

The start..=end syntax is a RangeInclusive:

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   ]); // This is a `RangeInclusive`

Implementations

impl<Idx> RangeInclusive<Idx>

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

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

Examples

use std::ops::RangeInclusive;

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

pub const fn start(&self) -> &Idx

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);

pub const fn end(&self) -> &Idx

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);

pub fn into_inner(self) -> (Idx, Idx)

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));

impl<Idx> RangeInclusive<Idx> where
    Idx: PartialOrd<Idx>, 

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

Returns true if item is contained in the range.

Examples

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));

This method always returns false after iteration has finished:

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

pub fn is_empty(&self) -> bool

Returns true if the range contains no items.

Examples

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

The range is empty if either side is incomparable:

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

This method returns true after iteration has finished:

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