1.26.0[−][src]Struct boolean_enums::lstd::ops::RangeInclusive
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]; assert_eq!(arr[ ..=2], [0,1,2 ]); assert_eq!(arr[1..=2], [ 1,2 ]); // RangeInclusive

[src]
impl<Idx> RangeInclusive<Idx>
ⓘImportant traits for RangeInclusive<A>
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));
ⓘImportant traits for &'a mut W
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);
ⓘImportant traits for &'a mut W
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);
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));

pub fn contains<U>(&self, item: &U) -> bool where | [src] |
🔬 This is a nightly-only experimental API. (range_contains
)
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)); assert!(!(0.0..=f32::NAN).contains(&0.0)); assert!(!(f32::NAN..=1.0).contains(&1.0));
pub fn is_empty(&self) -> bool | [src] |
🔬 This is a nightly-only experimental API. (range_is_empty
)
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());
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());
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());
