Struct alloy_eips::eip7702::Authorization

pub struct Authorization {
    pub chain_id: Uint<256, 4>,
    pub address: Address,
    pub nonce: u64,
}

An unsigned EIP-7702 authorization.

Fields

chain_id: Uint<256, 4>

The chain ID of the authorization.

address: Address

The address of the authorization.

nonce: u64

The nonce for the authorization.

Implementations

impl Authorization

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

Get the address for the authorization.

pub const 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]))

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

Convert to a signed authorization by adding a signature.

Trait Implementations

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<(), Error>

Formats the value using the given formatter.

impl Decodable for Authorization

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

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<Authorization, <__D as Deserializer<'de>>::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>(&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 Authorization

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
