Expand description
Defines an additive identity element for Self.
a + 0 = a ∀ a ∈ Self
0 + a = a ∀ a ∈ Self
Returns the additive identity element of Self, 0.
This function should return the same result at all times regardless of
external mutable state, for example values stored in TLS or in
static muts.
Returns true if self is equal to the additive identity.
Sets self to the additive identity element of Self, 0.
Returns the zero polynomial.
Checks if the given polynomial is zero.
Returns the zero polynomial.
Checks if the given polynomial is zero.
Returns the zero polynomial.
Checks if the given polynomial is zero.
Returns the point at infinity, which always has Z = 0.
Checks whether self.z.is_zero().
The identity element, or “zero”, of the group is the identity element of the multiplicative group of the underlying field, i.e., P::TargetField::one().
