pub struct BuilderSignature(pub PrimitiveSignature);

signature type for the builder

Tuple Fields

0: PrimitiveSignature

Methods from Deref<Target = PrimitiveSignature>

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

Returns the byte-array representation of this signature.

The first 32 bytes are the r value, the second 32 bytes the s value and the final byte is the v value in ‘Electrum’ notation.

pub fn as_erc2098(&self) -> [u8; 64]

Returns the ERC-2098 compact representation of this signature.

The first 32 bytes are the r value, and the next 32 bytes are the s value with yParity in the top bit of the s value, as described in ERC-2098.

See https://eips.ethereum.org/EIPS/eip-2098

pub fn normalize_s(&self) -> Option<PrimitiveSignature>

Normalizes the signature into “low S” form as described in BIP 0062: Dealing with Malleability.

If s is already normalized, returns None.

pub fn recid(&self) -> RecoveryId

Returns the recovery ID.

pub fn recover_address_from_msg<T>( &self, msg: T, ) -> Result<Address, SignatureError>

where T: AsRef<[u8]>,

Recovers an [Address] from this signature and the given message by first prefixing and hashing the message according to EIP-191.

pub fn recover_address_from_prehash( &self, prehash: &FixedBytes<32>, ) -> Result<Address, SignatureError>

Recovers an [Address] from this signature and the given prehashed message.

pub fn recover_from_msg<T>( &self, msg: T, ) -> Result<VerifyingKey<Secp256k1>, SignatureError>

where T: AsRef<[u8]>,

Recovers a VerifyingKey from this signature and the given message by first prefixing and hashing the message according to EIP-191.

pub fn recover_from_prehash( &self, prehash: &FixedBytes<32>, ) -> Result<VerifyingKey<Secp256k1>, SignatureError>

Recovers a VerifyingKey from this signature and the given prehashed message.

pub fn r(&self) -> Uint<256, 4>

Returns the r component of this signature.

pub fn s(&self) -> Uint<256, 4>

Returns the s component of this signature.

pub fn v(&self) -> bool

Returns the recovery ID as a bool.

pub fn rlp_rs_len(&self) -> usize

Length of RLP RS field encoding

pub fn write_rlp_rs(&self, out: &mut dyn BufMut)

Write R and S to an RLP buffer in progress.

pub fn write_rlp_vrs(&self, out: &mut dyn BufMut, v: impl Encodable)

Write the VRS to the output.

Trait Implementations

impl Clone for BuilderSignature

fn clone(&self) -> BuilderSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BuilderSignature

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

Formats the value using the given formatter.

impl Deref for BuilderSignature

type Target = PrimitiveSignature

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for BuilderSignature

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<BuilderSignature> for PrimitiveSignature

fn from(value: BuilderSignature) -> Self

Converts to this type from the input type.

impl From<PrimitiveSignature> for BuilderSignature

fn from(value: PrimitiveSignature) -> Self

Converts to this type from the input type.

impl Hash for BuilderSignature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BuilderSignature

fn eq(&self, other: &BuilderSignature) -> 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 BuilderSignature

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
