Expand description
The interface for a generic field.
Required methods
Returns the characteristic of the field.
fn double_in_place(&mut self)
fn double_in_place(&mut self)
Doubles self
in place.
fn square_in_place(&mut self) -> &mut Self
fn square_in_place(&mut self) -> &mut Self
Squares self
in place.
Computes the multiplicative inverse of self
if self
is nonzero.
fn inverse_in_place(&mut self) -> Option<&mut Self>
fn inverse_in_place(&mut self) -> Option<&mut Self>
Sets self
to self
’s inverse if it exists. Otherwise it is a no-op.
fn frobenius_map(&mut self, power: usize)
fn frobenius_map(&mut self, power: usize)
Exponentiates this element by a power of the base prime modulus via the Frobenius automorphism.
Returns a field element with an extra sign bit used for group parsing if the set of bytes forms a valid field element, otherwise returns None. This function is primarily intended for sampling random field elements from a hash-function or RNG output.
Provided methods
Exponentiates this element by a number represented with u64
limbs,
least significant limb first.
