Struct blstrs_plus::G2Affine
source · pub struct G2Affine(/* private fields */);
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§
source§impl G2Affine
impl G2Affine
sourcepub const COMPRESSED_BYTES: usize = 96usize
pub const COMPRESSED_BYTES: usize = 96usize
Bytes to represent this point compressed
sourcepub const UNCOMPRESSED_BYTES: usize = 192usize
pub const UNCOMPRESSED_BYTES: usize = 192usize
Bytes to represent this point uncompressed
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<Self>
pub fn from_uncompressed(bytes: &[u8; 192]) -> CtOption<Self>
Attempts to deserialize an uncompressed element.
sourcepub fn from_uncompressed_hex(hex: &str) -> CtOption<Self>
pub fn from_uncompressed_hex(hex: &str) -> CtOption<Self>
Attempts to deserialize a uncompressed element hex string. See notes::serialization
for details about how group elements are serialized.
sourcepub fn from_uncompressed_unchecked(bytes: &[u8; 192]) -> CtOption<Self>
pub fn from_uncompressed_unchecked(bytes: &[u8; 192]) -> CtOption<Self>
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<Self>
pub fn from_compressed(bytes: &[u8; 96]) -> CtOption<Self>
Attempts to deserialize a compressed element.
sourcepub fn from_compressed_hex(hex: &str) -> CtOption<Self>
pub fn from_compressed_hex(hex: &str) -> CtOption<Self>
Attempts to deserialize a compressed element hex string. See notes::serialization
for details about how group elements are serialized.
sourcepub fn from_compressed_unchecked(bytes: &[u8; 96]) -> CtOption<Self>
pub fn from_compressed_unchecked(bytes: &[u8; 96]) -> CtOption<Self>
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) -> Self
pub const fn uncompressed_size() -> usize
pub const fn compressed_size() -> usize
