Struct SignedAuthorization

pub struct SignedAuthorization { /* private fields */ }

A signed EIP-7702 authorization.

Implementations

impl SignedAuthorization

pub fn new_unchecked( inner: Authorization, y_parity: u8, r: U256, s: U256, ) -> Self

Creates a new signed authorization from raw signature values.

pub fn signature(&self) -> Result<Signature, SignatureError>

Gets the signature for the authorization. Returns SignatureError if signature could not be constructed from vrs values.

Note that this signature might still be invalid for recovery as it might have s value greater than secp256k1n/2.

pub const fn strip_signature(self) -> Authorization

Returns the inner Authorization.

pub const fn inner(&self) -> &Authorization

Returns the inner Authorization.

pub fn y_parity(&self) -> u8

Returns the signature parity value.

pub const fn r(&self) -> U256

Returns the signature r value.

pub const fn s(&self) -> U256

Returns the signature s value.

impl SignedAuthorization

pub fn recover_authority(&self) -> Result<Address, Eip7702Error>

Recover the authority for the authorization.

Note

Implementers should check that the authority has no code.

pub fn into_recovered(self) -> RecoveredAuthorization

Recover the authority and transform the signed authorization into a RecoveredAuthorization.

Methods from Deref<Target = Authorization>

pub fn chain_id(&self) -> &U256

Get the chain_id for the authorization.

Note

Implementers should check that this matches the current chain_id or is 0.

pub fn address(&self) -> &Address

Get the address for the authorization.

pub fn nonce(&self) -> u64

Get the nonce for the authorization.

pub fn signature_hash(&self) -> B256

Computes the signature hash used to sign the authorization, or recover the authority from a signed authorization list item.

The signature hash is keccak(MAGIC || rlp([chain_id, address, nonce]))

Trait Implementations

impl Clone for SignedAuthorization

fn clone(&self) -> SignedAuthorization

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignedAuthorization

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

Formats the value using the given formatter.

impl Decodable for SignedAuthorization

fn decode(buf: &mut &[u8]) -> Result<Self>

Decodes the blob into the appropriate type. buf must be advanced past the decoded object.

impl Deref for SignedAuthorization

type Target = Authorization

The resulting type after dereferencing.

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

Dereferences the value.

impl<'de> Deserialize<'de> for SignedAuthorization

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for SignedAuthorization

fn encode(&self, buf: &mut dyn BufMut)

Encodes the type into the out buffer.

fn length(&self) -> usize

Returns the length of the encoding of this type in bytes.

impl From<SignedAuthorization> for RecoveredAuthority

fn from(value: SignedAuthorization) -> Self

Converts to this type from the input type.

impl From<SignedAuthorization> for RecoveredAuthorization

fn from(value: SignedAuthorization) -> Self

Converts to this type from the input type.

impl Hash for SignedAuthorization

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 SignedAuthorization

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
