fn pop_back(self) -> (Self::Shorter, T)
[src]
Returns a new array without the last element, and the last element.
Example:
ⓘ
let a = arr![i32; 1, 2, 3, 4]; let (init, last) = a.pop_back(); assert_eq!(init, arr![i32; 1, 2, 3]); assert_eq!(last, 4);
fn pop_front(self) -> (T, Self::Shorter)
[src]
Returns a new array without the first element, and the first element. Example:
ⓘ
let a = arr![i32; 1, 2, 3, 4]; let (head, tail) = a.pop_front(); assert_eq!(head, 1); assert_eq!(tail, arr![i32; 2, 3, 4]);
