pub struct Secp256r1Signature { /* private fields */ }

Implementations

impl Secp256r1Signature

pub fn from_scalars(r: &[u8; 32], s: &[u8; 32]) -> Result<Self, CryptoError>

Creates a signature from the scalar values of r and s.

This method constructs a signature from the provided r and s values, which are expected to be 32-byte arrays each.

• Parameters:

  • r: The r scalar value as a 32-byte array.
  • s: The s scalar value as a 32-byte array.

• Returns: A Result<Secp256r1Signature, CryptoError>. Returns error if the values do not form a valid signature.

pub fn from_u256(r: U256, s: U256) -> Result<Self, CryptoError>

Creates a signature from U256 representations of r and s.

Converts the U256 values of r and s into byte arrays and attempts to create a signature. Assumes r and s are big-endian.

• Parameters:

  • r: The r value as a U256.
  • s: The s value as a U256.

• Returns: A Secp256r1Signature.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, CryptoError>

Constructs a Secp256r1Signature from a byte slice.

This method attempts to parse a 64-byte slice as an ECDSA signature. The first 32 bytes represent r and the following 32 bytes represent s. Returns an error if the slice is not 64 bytes long or does not represent a valid signature.

• Parameter bytes: A 64-byte slice representing the signature.

• Returns: A Result<Secp256r1Signature, CryptoError>.

pub fn to_bytes(&self) -> [u8; 64]

Converts the signature into a 64-byte array.

This method returns a byte array representation of the signature, with the first 32 bytes representing r and the last 32 bytes representing s.

• Returns: A 64-byte array representing the signature.

Trait Implementations

fn clone(&self) -> Secp256r1Signature

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Secp256r1Signature

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Secp256r1Signature

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Secp256r1Signature
