Struct reth_node_core::primitives::Signature
source · pub struct Signature {
pub r: Uint<256, 4>,
pub s: Uint<256, 4>,
pub odd_y_parity: bool,
}
Expand description
r, s: Values corresponding to the signature of the transaction and used to determine the sender of the transaction; formally Tr and Ts. This is expanded in Appendix F of yellow paper.
This type is unaware of the chain id, and thus shouldn’t be used when encoding or decoding
legacy transactions. Use SignatureWithParity
instead.
Fields§
§r: Uint<256, 4>
The R field of the signature; the point on the curve.
s: Uint<256, 4>
The S field of the signature; the point on the curve.
odd_y_parity: bool
yParity: Signature Y parity; formally Ty
WARNING: if it’s deprecated in favor of alloy_primitives::Signature
be sure that parity
storage deser matches.
Implementations§
source§impl Signature
impl Signature
sourcepub fn payload_len(&self) -> usize
pub fn payload_len(&self) -> usize
Output the length of the signature without the length of the RLP header
sourcepub fn encode(&self, out: &mut dyn BufMut)
pub fn encode(&self, out: &mut dyn BufMut)
Encode the odd_y_parity
, r
, s
values without a RLP header.
sourcepub fn decode(buf: &mut &[u8]) -> Result<Signature, Error>
pub fn decode(buf: &mut &[u8]) -> Result<Signature, Error>
Decodes the odd_y_parity
, r
, s
values without a RLP header.
sourcepub fn recover_signer_unchecked(&self, hash: FixedBytes<32>) -> Option<Address>
pub fn recover_signer_unchecked(&self, hash: FixedBytes<32>) -> Option<Address>
Recover signer from message hash, without ensuring that the signature has a low s
value.
Using this for signature validation will succeed, even if the signature is malleable or not
compliant with EIP-2. This is provided for compatibility with old signatures which have
large s
values.
sourcepub fn recover_signer(&self, hash: FixedBytes<32>) -> Option<Address>
pub fn recover_signer(&self, hash: FixedBytes<32>) -> Option<Address>
Recover signer address from message hash. This ensures that the signature S value is
greater than secp256k1n / 2
, as specified in
EIP-2.
If the S value is too large, then this will return None
sourcepub fn to_hex_bytes(&self) -> Bytes
pub fn to_hex_bytes(&self) -> Bytes
Turn this signature into its hex-encoded representation.
sourcepub const fn size(&self) -> usize
pub const fn size(&self) -> usize
Calculates a heuristic for the in-memory size of the Signature.
sourcepub fn legacy_parity(&self, chain_id: Option<u64>) -> Parity
pub fn legacy_parity(&self, chain_id: Option<u64>) -> Parity
Returns Parity value based on chain_id
for legacy transaction signature.
sourcepub const fn optimism_deposit_tx_signature() -> Signature
Available on crate feature optimism
only.
pub const fn optimism_deposit_tx_signature() -> Signature
optimism
only.Returns the signature for the optimism deposit transactions, which don’t include a signature.
