Module range

🔬This is a nightly-only experimental API. (new_range_api)

Experimental replacement range types

The types within this module are meant to replace the existing Range, RangeInclusive, and RangeFrom types in a future edition.

#![feature(new_range_api)]
use core::range::{Range, RangeFrom, RangeInclusive};

let arr = [0, 1, 2, 3, 4];
assert_eq!(arr[                      ..   ], [0, 1, 2, 3, 4]);
assert_eq!(arr[                      .. 3 ], [0, 1, 2      ]);
assert_eq!(arr[                      ..=3 ], [0, 1, 2, 3   ]);
assert_eq!(arr[     RangeFrom::from(1..  )], [   1, 2, 3, 4]);
assert_eq!(arr[         Range::from(1..3 )], [   1, 2      ]);
assert_eq!(arr[RangeInclusive::from(1..=3)], [   1, 2, 3   ]);
