[−][src]Struct dusk_bls12_381::G2Affine
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.
Values of G2Affine
are guaranteed to be in the $q$-order subgroup unless an
"unchecked" API was misused.
Methods
impl G2Affine
[src]
pub fn identity() -> G2Affine
[src]
Returns the identity of the group: the point at infinity.
pub fn generator() -> G2Affine
[src]
Returns a fixed generator of the group. See notes::design
for how this generator is chosen.
pub fn to_compressed(&self) -> [u8; 96]
[src]
Serializes this element into compressed form. See notes::serialization
for details about how group elements are serialized.
pub fn to_uncompressed(&self) -> [u8; 192]
[src]
Serializes this element into uncompressed form. See notes::serialization
for details about how group elements are serialized.
pub fn from_uncompressed(bytes: &[u8; 192]) -> CtOption<Self>
[src]
Attempts to deserialize an uncompressed element. See notes::serialization
for details about how group elements are serialized.
pub fn from_uncompressed_unchecked(bytes: &[u8; 192]) -> CtOption<Self>
[src]
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; 96]) -> CtOption<Self>
[src]
Attempts to deserialize a compressed element. See notes::serialization
for details about how group elements are serialized.
pub fn from_compressed_unchecked(bytes: &[u8; 96]) -> CtOption<Self>
[src]
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 is_identity(&self) -> Choice
[src]
Returns true if this element is the identity (the point at infinity).
pub fn is_torsion_free(&self) -> Choice
[src]
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.
pub fn is_on_curve(&self) -> Choice
[src]
Returns true if this point is on the curve. This should always return true unless an "unchecked" API was used.
