Methods

impl G1

pub const COMPRESSED_BYTES: usize

This is supported on feature="bls" only.

The bytes in G1 compressed form

pub const UNCOMPRESSED_BYTES: usize

This is supported on feature="bls" only.

The bytes in G1 uncompressed form

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

This is supported on feature="bls" only.

Serialize the point to compressed bytes in big endian form Only the x-coordinate

NOTE: Must use GenericArray due to rust error error[E0277]: arrays only have std trait implementations for lengths 0..=32 The caller can use section 4.3 in https://tools.ietf.org/id/draft-jivsov-ecc-compact-05.html to reconstruct Y if needed

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

This is supported on feature="bls" only.

Serialize the point to uncompressed bytes in big endian form The x-coordinate followed by the y-coordinate NOTE: Must use GenericArray due to rust error error[E0277]: arrays only have std trait implementations for lengths 0..=32

pub fn encode_to_hex(&self) -> String

This is supported on feature="bls" only.

Serialize the point to compressed lower hex string Only the x-coordinate

pub fn encode_to_hex_uncompressed(&self) -> String

This is supported on feature="bls" only.

Serialize the point to uncompressed lower hex string The x-coordinate followed by the y-coordinate

pub fn decode_from_hex_points(x: &str, y: &str) -> Result<Self, String>

This is supported on feature="bls" only.

Convenience method when x and y are supplied separately

pub fn from_byte_points<B: AsRef<[u8]>>(x: B, y: B) -> Result<G1, String>

This is supported on feature="bls" only.

Convenience method when x and y are supplied separately
