Struct alloy_eips::eip7702::Authorization

pub struct Authorization {
    pub chain_id: ChainId,
    pub address: Address,
    pub nonce: OptionalNonce,
}

An unsigned EIP-7702 authorization.

Fields

chain_id: ChainId

The chain ID of the authorization.

address: Address

The address of the authorization.

nonce: OptionalNonce

The nonce for the authorization.

Implementations

impl Authorization

pub const fn chain_id(&self) -> ChainId

Get the chain_id for the authorization.

Note

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

pub const fn address(&self) -> &Address

Get the address for the authorization.

pub fn nonce(&self) -> Option<u64>

Get the nonce for the authorization.

Note

If this is Some, implementers should check that the nonce of the authority is equal to this nonce.

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, [nonce], address]))

pub const fn into_signed(self, signature: Signature) -> SignedAuthorization

Convert to a signed authorization by adding a signature.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for Authorization

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

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

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

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 Authorization

fn clone(&self) -> Authorization

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Authorization

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

Formats the value using the given formatter.

impl Decodable for Authorization

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

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

impl<'de> Deserialize<'de> for Authorization

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for Authorization

fn length(&self) -> usize

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

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

Encodes the type into the out buffer.

impl Hash for Authorization

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 Authorization

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
