Trait ModPowerOf2SubMul 

pub trait ModPowerOf2SubMul<Y = Self, Z = Self> {
    type Output;

    // Required method
    fn mod_power_of_2_sub_mul(self, y: Y, z: Z, pow: u64) -> Self::Output;
}

Subtracts the product of two numbers from a number, modulo $2^k$. All three inputs must be already reduced modulo $2^k$.

Required Associated Types

type Output

Required Methods

fn mod_power_of_2_sub_mul(self, y: Y, z: Z, pow: u64) -> Self::Output

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl ModPowerOf2SubMul for u8

fn mod_power_of_2_sub_mul(self, y: u8, z: u8, pow: u64) -> u8

Subtracts the product of two numbers from a third number, modulo a fourth number $2^k$. All three inputs must be already reduced modulo $2^k$.

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

Worst-case complexity

Constant time and additional memory.

Panics

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