Struct core::ops::RangeFull
[−]
[src]
pub struct RangeFull;1.0.0
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 ]); }
