Enum Signature 

pub enum Signature {
    Ed25519([u8; 64]),
    Secp256k1([u8; 65]),
}

Cryptographic signature.

Variants

Ed25519([u8; 64])

Ed25519 signature (64 bytes).

Secp256k1([u8; 65])

Secp256k1 signature (65 bytes: [r (32) | s (32) | v (1)]).

Implementations

impl Signature

pub fn ed25519_from_bytes(bytes: [u8; 64]) -> Self

Create an Ed25519 signature from raw 64 bytes.

pub fn secp256k1_from_bytes(bytes: [u8; 65]) -> Self

Create a Secp256k1 signature from raw 65 bytes.

The format is [r (32 bytes) | s (32 bytes) | v (1 byte recovery id)], matching the NEAR protocol’s secp256k1 signature format.

pub fn key_type(&self) -> KeyType

Get the key type.

pub fn as_bytes(&self) -> &[u8]

Get the raw signature bytes.

pub fn verify(&self, message: &[u8], public_key: &PublicKey) -> bool

Verify this signature against a message and public key.

Trait Implementations

impl BorshDeserialize for Signature

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for Signature

fn serialize<W: Write>(&self, writer: &mut W) -> Result<()>

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Signature

where Self: FromStr, <Self as FromStr>::Err: Display,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

Formats the value using the given formatter.

impl FromStr for Signature

type Err = ParseKeyError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for Signature

fn eq(&self, other: &Signature) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Signature

where Self: Display,

fn serialize<__S>(&self, serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Signature

impl StructuralPartialEq for Signature
