Struct SignedAuthorization

pub struct SignedAuthorization { /* private fields */ }

A signed EIP-7702 authorization.

Implementations

impl SignedAuthorization

pub const fn signature(&self) -> &Signature

Get the signature for the authorization.

pub const fn into_parts(self) -> (Authorization, Signature)

Splits the authorization into parts.

impl SignedAuthorization

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

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) -> Uint<256, 4>

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) -> FixedBytes<32>

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<'a> Arbitrary<'a> for SignedAuthorization

fn arbitrary(u: &mut Unstructured<'a>) -> Result<SignedAuthorization, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

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<(), Error>

Formats the value using the given formatter.

impl Decodable for SignedAuthorization

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

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) -> &<SignedAuthorization as Deref>::Target

Dereferences the value.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<SignedAuthorization, <__D as Deserializer<'de>>::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 RecoveredAuthorization

fn from(signed_auth: SignedAuthorization) -> Self

Converts to this type from the input type.

impl Hash for SignedAuthorization

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

where H: Hasher,

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 as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SignedAuthorization
