pub struct G2Affine(_);
Expand description
This is an element of $\mathbb{G}_2$ represented in the affine coordinate space. It is ideal to keep elements in this representation to reduce memory usage and improve performance through the use of mixed curve model arithmetic.
Implementations
sourceimpl G2Affine
impl G2Affine
sourcepub fn to_compressed(&self) -> [u8; 96]
pub fn to_compressed(&self) -> [u8; 96]
Serializes this element into compressed form.
sourcepub fn to_uncompressed(&self) -> [u8; 192]
pub fn to_uncompressed(&self) -> [u8; 192]
Serializes this element into uncompressed form.
sourcepub fn from_uncompressed(bytes: &[u8; 192]) -> CtOption<G2Affine>
pub fn from_uncompressed(bytes: &[u8; 192]) -> CtOption<G2Affine>
Attempts to deserialize an uncompressed element.
sourcepub fn from_uncompressed_unchecked(bytes: &[u8; 192]) -> CtOption<G2Affine>
pub fn from_uncompressed_unchecked(bytes: &[u8; 192]) -> CtOption<G2Affine>
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.
sourcepub fn from_compressed(bytes: &[u8; 96]) -> CtOption<G2Affine>
pub fn from_compressed(bytes: &[u8; 96]) -> CtOption<G2Affine>
Attempts to deserialize a compressed element.
sourcepub fn from_compressed_unchecked(bytes: &[u8; 96]) -> CtOption<G2Affine>
pub fn from_compressed_unchecked(bytes: &[u8; 96]) -> CtOption<G2Affine>
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.
sourcepub fn is_torsion_free(&self) -> Choice
pub fn is_torsion_free(&self) -> Choice
Returns true if this point is free of an $h$-torsion component, and so it exists within the $q$-order subgroup $\mathbb{G}_2$. This should always return true unless an “unchecked” API was used.
sourcepub fn is_on_curve(&self) -> Choice
pub fn is_on_curve(&self) -> Choice
Returns true if this point is on the curve. This should always return true unless an “unchecked” API was used.
pub fn from_raw_unchecked(x: Fp2, y: Fp2, _infinity: bool) -> G2Affine
pub const fn uncompressed_size() -> usize
pub const fn compressed_size() -> usize
