Struct nom::lib::std::ops::RangeInclusive1.26.0[][src]

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  ]);  // RangeInclusive

Methods

impl<Idx> RangeInclusive<Idx>
[src]

Important traits for RangeInclusive<A>

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 R

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 R

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);

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>, 
[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));

🔬 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());
