Struct Authorization

pub struct Authorization {
    pub chain_id: u64,
    pub address: Address,
    pub nonce: u64,
}

An unsigned EIP-7702 authorization.

Fields

chain_id: u64

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) -> u64

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<'arbitrary> Arbitrary<'arbitrary> for Authorization

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

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

fn arbitrary_take_rest( u: Unstructured<'arbitrary>, ) -> Result<Authorization, 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.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

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 Compact for Authorization

fn to_compact<B>(&self, buf: &mut B) -> usize

where B: BufMut + AsMut<[u8]>,

Takes a buffer which can be written to. Ideally, it returns the length written to.

fn from_compact(buf: &[u8], len: usize) -> (Authorization, &[u8])

Takes a buffer which can be read from. Returns the object and buf with its internal cursor advanced (eg..advance(len)).

fn specialized_to_compact<B>(&self, buf: &mut B) -> usize

where B: BufMut + AsMut<[u8]>,

“Optional”: If there’s no good reason to use it, don’t.

fn specialized_from_compact(buf: &[u8], len: usize) -> (Self, &[u8])

“Optional”: If there’s no good reason to use it, don’t.

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Authorization

impl StructuralPartialEq for Authorization

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
