pub struct ProjectivePoint { /* private fields */ }
Available on crate feature arithmetic only.
Expand description

A point on the secp256k1 curve in projective coordinates.

Implementations

Additive identity of the group: the point at infinity.

Base point of secp256k1.

👎 Deprecated since 0.10.2:

use ProjectivePoint::IDENTITY instead

Returns the additive identity of SECP256k1, also known as the “neutral element” or “point at infinity”.

👎 Deprecated since 0.10.2:

use ProjectivePoint::GENERATOR instead

Returns the base point of SECP256k1.

Returns the affine representation of this point, or None if it is the identity.

Doubles this point.

Calculates SECP256k1 endomorphism: self * lambda.
