Trait numeric_array::Shorten

pub trait Shorten<T>: NumericSequence<T> {
    type Shorter: Lengthen<T, Longer = Self>;
    fn shorten(self) -> (Self::Shorter, T);
}

Defines a NumericSequence which can be shortened by removing the last element in it.

Additionally, any shortened sequence can be lengthened by adding an element to the end of it.

Associated Types

type Shorter: Lengthen<T, Longer = Self>

NumericSequence that has one less element than Self

Required Methods

fn shorten(self) -> (Self::Shorter, T)

Moves all but the last element into a NumericArray with one less element than the current one.

Example:

let a = NumericArray::new(arr![i32; 1, 2, 3, 4]);
let b = NumericArray::new(arr![i32; 1, 2, 3]);

assert_eq!(a.shorten().0, b);
