Struct TempoSignedAuthorization 

pub struct TempoSignedAuthorization {
    inner: Authorization,
    signature: TempoSignature,
}

A signed EIP-7702 authorization with AA signature support.

This is a 1:1 parallel to alloy’s SignedAuthorization, but using TempoSignature instead of hardcoded (y_parity, r, s) components. This allows supporting multiple signature types: Secp256k1, P256, and WebAuthn.

The structure and methods mirror SignedAuthorization exactly to maintain compatibility with the EIP-7702 spec.

Fields

inner: Authorization

Inner authorization (reuses alloy’s Authorization)

signature: TempoSignature

The AA signature (Secp256k1, P256, or WebAuthn)

Implementations

impl TempoSignedAuthorization

pub const fn new_unchecked( inner: Authorization, signature: TempoSignature, ) -> Self

Creates a new signed authorization from an authorization and signature.

This is the unchecked version - signature is not validated.

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

Gets the signature for the authorization.

Returns a reference to the AA signature, which can be Secp256k1, P256, or WebAuthn.

pub fn strip_signature(self) -> Authorization

Returns the inner Authorization.

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

Returns a reference to the inner Authorization.

pub fn signature_hash(&self) -> B256

Computes the signature hash used to sign the authorization.

The signature hash is keccak(MAGIC || rlp([chain_id, address, nonce])) following EIP-7702 spec.

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

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].

fn decode_fields(buf: &mut &[u8]) -> RlpResult<Self>

Decodes the authorization from RLP bytes, including the signature.

fn fields_len(&self) -> usize

Outputs the length of the authorization’s fields, without a RLP header.

pub fn size(&self) -> usize

Calculates a heuristic for the in-memory size of this authorization

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<'arbitrary> Arbitrary<'arbitrary> for TempoSignedAuthorization

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.

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

impl Clone for TempoSignedAuthorization

fn clone(&self) -> TempoSignedAuthorization

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Compact for TempoSignedAuthorization

Available on crate feature reth-codec only.

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) -> (Self, &[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 TempoSignedAuthorization

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

Formats the value using the given formatter.

impl Decodable for TempoSignedAuthorization

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

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

impl Deref for TempoSignedAuthorization

type Target = Authorization

The resulting type after dereferencing.

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

Dereferences the value.

impl<'de> Deserialize<'de> for TempoSignedAuthorization

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for TempoSignedAuthorization

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 Hash for TempoSignedAuthorization

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 TempoSignedAuthorization

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TempoSignedAuthorization

impl StructuralPartialEq for TempoSignedAuthorization

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.
