fn append(self, last: T) -> Self::Longer
[src]
Returns a new array with the given element appended to the end of it.
Example:
ⓘ
let a = arr![i32; 1, 2, 3]; let b = a.append(4); assert_eq!(b, arr![i32; 1, 2, 3, 4]);
fn prepend(self, first: T) -> Self::Longer
[src]
Returns a new array with the given element prepended to the front of it.
Example:
ⓘ
let a = arr![i32; 1, 2, 3]; let b = a.prepend(4); assert_eq!(b, arr![i32; 4, 1, 2, 3]);
