Struct sp_std::ops::RangeInclusive

1.26.0 · source ·
pub struct RangeInclusive<Idx> { /* private fields */ }
Expand description

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§

source§

impl<Idx> RangeInclusive<Idx>

1.27.0 (const: 1.32.0) · source

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));
1.27.0 (const: 1.32.0) · source

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);
1.27.0 (const: 1.32.0) · source

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);
1.27.0 (const: unstable) · source

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));
source§

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

1.35.0 (const: unstable) · source

pub fn contains<U>(&self, item: &U) -> boolwhere 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));
1.47.0 (const: unstable) · source

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());

🔬This is a nightly-only experimental API. (slice_index_methods)
Returns a shared reference to the output at this location, without performing any bounds checking. Calling this method with an out-of-bounds index or a dangling slice pointer is undefined behavior even if the resulting reference is not used.
const: unstable · source§

unsafe fn get_unchecked_mut(self, slice: *mut [T]) -> *mut [T]

🔬This is a nightly-only experimental API. (slice_index_methods)
Returns a mutable reference to the output at this location, without performing any bounds checking. Calling this method with an out-of-bounds index or a dangling slice pointer is undefined behavior even if the resulting reference is not used.

fn index(self, slice: &[T]) -> &[T]

🔬This is a nightly-only experimental API. (slice_index_methods)
Returns a shared reference to the output at this location, panicking if out of bounds.

fn index_mut(self, slice: &mut [T]) -> &mut [T]

🔬This is a nightly-only experimental API. (slice_index_methods)

impl SliceIndex<str> for RangeInclusive<usize>

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.
