Types that implement this trait are finite rings.
Required Associated Constants
Required Methods
sourcefn from_uniform_bytes(x: &[u8; 16]) -> Self
fn from_uniform_bytes(x: &[u8; 16]) -> Self
Construct an element from the given uniformly chosen random bytes.
Provided Methods
sourcefn random_nonzero<R: Rng + ?Sized>(rng: &mut R) -> Self
fn random_nonzero<R: Rng + ?Sized>(rng: &mut R) -> Self
Generate a random non-zero element.
Compute self to the power of n.
Constant-Time
This function will execute in constant-time, regardless of n’s value.
sourcefn pow_bounded(&self, n: u128, bound: u16) -> Self
fn pow_bounded(&self, n: u128, bound: u16) -> Self
Compute self to the power of n, where n is guaranteed to be <= 2^bound.
Constant-Time
This function is constant time in n, but not constant time in bound.
sourcefn pow_var_time(&self, n: u128) -> Self
fn pow_var_time(&self, n: u128) -> Self
Compute self to the power of n, in non-constant time.
