Methods
impl Affine[src]
fn set_xy(&mut self, x: &Field, y: &Field)[src]
Set a group element equal to the point with given X and Y coordinates.
fn set_xquad(&mut self, x: &Field) -> bool[src]
Set a group element (affine) equal to the point with the given X coordinate and a Y coordinate that is a quadratic residue modulo p. The return value is true iff a coordinate with the given X coordinate exists.
fn set_xo_var(&mut self, x: &Field, odd: bool) -> bool[src]
Set a group element (affine) equal to the point with the given X coordinate, and given oddness for Y. Return value indicates whether the result is valid.
fn is_infinity(&self) -> bool[src]
Check whether a group element is the point at infinity.
fn is_valid_var(&self) -> bool[src]
Check whether a group element is valid (i.e., on the curve).
fn neg_in_place(&mut self, other: &Affine)[src]
fn neg(&self) -> Affine[src]
fn set_gej(&mut self, a: &Jacobian)[src]
Set a group element equal to another which is given in jacobian coordinates.
fn set_gej_var(&mut self, a: &Jacobian)[src]
fn set_gej_zinv(&mut self, a: &Jacobian, zi: &Field)[src]
fn clear(&mut self)[src]
Clear a secp256k1_ge to prevent leaking sensitive information.
