This corresponds to EC_POINT_point2hex.

pub fn to_owned(&self, group: &EcGroupRef) -> Result<EcPoint, ErrorStack>

Creates a new point on the specified curve with the same value.

This corresponds to EC_POINT_dup.

pub fn eq( &self, group: &EcGroupRef, other: &EcPointRef, ctx: &mut BigNumContextRef, ) -> Result<bool, ErrorStack>

Determines if this point is equal to another.

This corresponds to EC_POINT_cmp.

pub fn affine_coordinates( &self, group: &EcGroupRef, x: &mut BigNumRef, y: &mut BigNumRef, ctx: &mut BigNumContextRef, ) -> Result<(), ErrorStack>

Places affine coordinates of a curve over a prime field in the provided x and y BigNums.

This corresponds to EC_POINT_get_affine_coordinates.

pub fn affine_coordinates_gfp( &self, group: &EcGroupRef, x: &mut BigNumRef, y: &mut BigNumRef, ctx: &mut BigNumContextRef, ) -> Result<(), ErrorStack>

Places affine coordinates of a curve over a prime field in the provided x and y BigNums

This corresponds to EC_POINT_get_affine_coordinates_GFp.

pub fn set_affine_coordinates_gfp( &mut self, group: &EcGroupRef, x: &BigNumRef, y: &BigNumRef, ctx: &mut BigNumContextRef, ) -> Result<(), ErrorStack>

Sets affine coordinates of a curve over a prime field using the provided x and y BigNums

This corresponds to EC_POINT_set_affine_coordinates_GFp.

pub fn affine_coordinates_gf2m( &self, group: &EcGroupRef, x: &mut BigNumRef, y: &mut BigNumRef, ctx: &mut BigNumContextRef, ) -> Result<(), ErrorStack>

Places affine coordinates of a curve over a binary field in the provided x and y BigNums

This corresponds to EC_POINT_get_affine_coordinates_GF2m.

pub fn is_infinity(&self, group: &EcGroupRef) -> bool

Checks if point is infinity

This corresponds to EC_POINT_is_at_infinity.

pub fn is_on_curve( &self, group: &EcGroupRef, ctx: &mut BigNumContextRef, ) -> Result<bool, ErrorStack>

Checks if point is on a given curve

This corresponds to EC_POINT_is_on_curve.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
