Enum std::ops::RangeInclusive [−] [src]

pub enum RangeInclusive<Idx> {
    Empty {
        at: Idx,
    },
    NonEmpty {
        start: Idx,
        end: Idx,
    },
}

Unstable (inclusive_range #28237)
: recently added, follows RFC

An inclusive range which is bounded at both ends: { x | start <= x <= end }. Use start...end (three dots) for its shorthand.

See the contains() method for its characterization.

Examples

#![feature(inclusive_range,inclusive_range_syntax,iter_arith)] fn main() { assert_eq!((3...5), std::ops::RangeInclusive::NonEmpty{ start: 3, end: 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 }

#![feature(inclusive_range,inclusive_range_syntax,iter_arith)]
fn main() {
    assert_eq!((3...5), std::ops::RangeInclusive::NonEmpty{ start: 3, end: 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
}

Variants

Empty

Unstable (inclusive_range #28237)
: recently added, follows RFC

Empty range (iteration has finished)

Fields

at: Idx

Unstable (inclusive_range #28237)
: recently added, follows RFC

NonEmpty

Unstable (inclusive_range #28237)
: recently added, follows RFC

Non-empty range (iteration will yield value(s))

Fields

`start: Idx`	Unstable (`inclusive_range` #28237) : recently added, follows RFC
`end: Idx`	Unstable (`inclusive_range` #28237) : recently added, follows RFC

Methods

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

`fn contains(&self, item: Idx) -> bool`

Unstable (range_contains #32311)
: recently added as per RFC

Examples

#![feature(range_contains,inclusive_range_syntax)] fn main() { 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)); }

#![feature(range_contains,inclusive_range_syntax)]
fn main() {
    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));
}

`impl<A> RangeInclusive<A> where A: Step`

`fn step_by(self, by: A) -> StepBy<A, RangeInclusive<A>>`

Unstable (step_by #27741)
: recent addition

Creates an iterator with the same range, but stepping by the given amount at each iteration.

The resulting iterator handles overflow by stopping.

Examples

#![feature(step_by, inclusive_range_syntax)] fn main() { for i in (0...10).step_by(2) { println!("{}", i); } }

#![feature(step_by, inclusive_range_syntax)]

for i in (0...10).step_by(2) {
    println!("{}", i);
}

This prints:

Trait Implementations

`impl<Idx> Debug for RangeInclusive<Idx> where Idx: Debug`

`fn fmt(&self, fmt: &mut Formatter) -> Result<(), Error>`

Formats the value using the given formatter.

`impl<Idx> From<Range<Idx>> for RangeInclusive<Idx> where Idx: One + Sub<Idx, Output=Idx> + PartialOrd<Idx>`
