Implementations on Foreign Types

impl Gcd for u8

fn gcd(self, other: u8) -> u8

Computes the GCD (greatest common divisor) of two numbers.

The GCD of 0 and $n$, for any $n$, is 0. In particular, $\gcd(0, 0) = 0$, which makes sense if we interpret “greatest” to mean “greatest by the divisibility order”.

$$ f(x, y) = \gcd(x, y). $$

Worst-case complexity

$T(n) = O(n^2)$

$M(n) = O(n)$

where $T$ is time, $M$ is additional memory, and $n$ is max(self.significant_bits(), other.significant_bits()).

Examples
