Implementations

impl G1Projective

pub fn to_compressed(&self) -> [u8; 48]

Serializes this element into compressed form.

pub fn to_uncompressed(&self) -> [u8; 96]

Serializes this element into uncompressed form.

pub fn from_uncompressed(bytes: &[u8; 96]) -> Option<G1Projective>

Attempts to deserialize an uncompressed element.

pub fn from_uncompressed_unchecked(bytes: &[u8; 96]) -> Option<G1Projective>

Attempts to deserialize an uncompressed element, not checking if the element is on the curve and not checking if it is in the correct subgroup.

This is dangerous to call unless you trust the bytes you are reading; otherwise, API invariants may be broken. Please consider using from_uncompressed() instead.

pub fn from_compressed(bytes: &[u8; 48]) -> Option<G1Projective>

Attempts to deserialize a compressed element.

pub fn from_compressed_unchecked(bytes: &[u8; 48]) -> Option<G1Projective>

Attempts to deserialize an uncompressed element, not checking if the element is in the correct subgroup.

This is dangerous to call unless you trust the bytes you are reading; otherwise, API invariants may be broken. Please consider using from_compressed() instead.

pub fn add(&self, rhs: &G1Projective) -> G1Projective

Adds this point to another point.

pub fn add_mixed(&self, rhs: &G1Affine) -> G1Projective

Adds this point to another point in the affine model.

pub fn is_on_curve(&self) -> bool

pub fn x(&self) -> Fp

Returns the x coordinate.

pub fn y(&self) -> Fp
