impl ModPowerOf2Square for u8

fn mod_power_of_2_square(self, pow: u64) -> u8

Squares a number modulo another number $2^k$. The input must be already reduced modulo $2^k$.

$f(x, k) = y$, where $x, y < 2^k$ and $x^2 \equiv y \mod 2^k$.

Worst-case complexity

Constant time and additional memory.

Panics

Panics if pow is greater than Self::WIDTH or if self is greater than or equal to $2^k$.

Examples
