Struct EthereumSignature 

pub struct EthereumSignature {
    pub r: [u8; 32],
    pub s: [u8; 32],
    pub v: u64,
}

An Ethereum ECDSA signature with recovery ID.

Fields

r: [u8; 32]

The R component (32 bytes).

s: [u8; 32]

The S component (32 bytes), guaranteed to be low-S (EIP-2).

v: u64

Recovery ID: 27 or 28 (legacy), or chain_id * 2 + 35 + rec_id (EIP-155). Stored as u64 to support high chain IDs (Polygon=137, Arbitrum=42161, etc.).

Implementations

impl EthereumSignature

pub fn to_bytes(&self) -> [u8; 65]

Encode as 65-byte r || s || v (legacy, v truncated to u8).

For EIP-155 signatures with high chain IDs, use to_bytes_eip155() instead.

pub fn to_bytes_eip155(&self) -> Vec<u8>

Encode as r (32) || s (32) || v (8 bytes BE) for EIP-155 with large chain IDs.

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

Decode from 65-byte r || s || v (v as single byte).

pub fn recovery_bit(&self) -> u8

Extract the recovery bit (0 or 1) from v, handling both legacy (v=27/28) and EIP-155 (v = chain_id*2 + 35 + {0,1}).

Trait Implementations

impl Clone for EthereumSignature

fn clone(&self) -> EthereumSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EthereumSignature

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

Formats the value using the given formatter.

impl Display for EthereumSignature

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

Formats the value using the given formatter.

impl PartialEq for EthereumSignature

fn eq(&self, other: &EthereumSignature) -> 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.
