Trait wiwi::num::Widening

pub trait Widening<Wide>: Base {
    // Required methods
    fn widen(self) -> Wide;
    fn split(wide: Wide) -> (Self, Self);
    fn join(self, n_high: Self) -> Wide;
}

Numbers that can be “widened” to another number type that’s double its size

Required Methods

fn widen(self) -> Wide

Extend self out into the widened type (without changing its value)

fn split(wide: Wide) -> (Self, Self)

Splits the wide integer into its lower and upper Self parts

The returned value is (low, high), ie. first element is the lower half, and the second element is the upper half, ie. little endian order.

fn join(self, n_high: Self) -> Wide

Joins self with an upper value, to give a widened value

Object Safety

This trait is not object safe.
