Struct alloc_data::prelude::ops::RangeFull

1.0.0 · source · [−]

pub struct RangeFull;

Expand description

An unbounded range (..).

RangeFull is primarily used as a slicing index, its shorthand is ... It cannot serve as an Iterator because it doesn’t have a starting point.

Examples

The .. syntax is a RangeFull:

assert_eq!((..), std::ops::RangeFull);

It does not have an IntoIterator implementation, so you can’t use it in a for loop directly. This won’t compile:

for i in .. {
    // ...
}

Used as a slicing index, RangeFull produces the full array as a slice.

let arr = [0, 1, 2, 3, 4];
assert_eq!(arr[ ..  ], [0, 1, 2, 3, 4]); // This is the `RangeFull`
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   ]);

1.20.0 (const: unstable) · source

impl SliceIndex<str> for RangeFull

Implements substring slicing with syntax &self[..] or &mut self[..].

Returns a slice of the whole string, i.e., returns &self or &mut self. Equivalent to &self[0 .. len] or &mut self[0 .. len]. Unlike other indexing operations, this can never panic.

This operation is O(1).

Prior to 1.20.0, these indexing operations were still supported by direct implementation of Index and IndexMut.

Equivalent to &self[0 .. len] or &mut self[0 .. len].

type Output = str

The output type returned by methods.
