Struct std::ops::RangeFull

pub struct RangeFull;

An unbounded range. Use .. (two dots) for its shorthand.

Its primary use case is slicing index. It cannot serve as an iterator because it doesn't have a starting point.

Examples

fn main() { assert_eq!((..), std::ops::RangeFull); let arr = [0, 1, 2, 3]; assert_eq!(arr[ .. ], [0,1,2,3]); // RangeFull assert_eq!(arr[ ..3], [0,1,2 ]); assert_eq!(arr[1.. ], [ 1,2,3]); assert_eq!(arr[1..3], [ 1,2 ]); }

fn main() {
    assert_eq!((..), std::ops::RangeFull);

    let arr = [0, 1, 2, 3];
    assert_eq!(arr[ .. ], [0,1,2,3]);  // RangeFull
    assert_eq!(arr[ ..3], [0,1,2  ]);
    assert_eq!(arr[1.. ], [  1,2,3]);
    assert_eq!(arr[1..3], [  1,2  ]);
}
