Struct SignedKeyAuthorization 

pub struct SignedKeyAuthorization {
    pub authorization: KeyAuthorization,
    pub signature: PrimitiveSignature,
}

Signed key authorization that can be attached to a transaction.

Fields

authorization: KeyAuthorization

Key authorization for provisioning access keys

signature: PrimitiveSignature

Signature authorizing this key (signed by root key)

Implementations

impl SignedKeyAuthorization

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

Recover the signer of the KeyAuthorization.

pub fn size(&self) -> usize

Calculates a heuristic for the in-memory size of the signed key authorization

Methods from Deref<Target = KeyAuthorization>

pub fn signature_hash(&self) -> FixedBytes<32>

Computes the authorization message hash for this key authorization.

pub fn has_unlimited_spending(&self) -> bool

Returns whether this key has unlimited spending (limits is None)

pub fn never_expires(&self) -> bool

Returns whether this key never expires (expiry is None)

pub fn validate_chain_id( &self, expected_chain_id: u64, is_t1c: bool, ) -> Result<(), KeyAuthorizationChainIdError>

Validates that this key authorization’s chain_id is compatible with expected_chain_id.

• Post-T1C: chain_id must exactly match (wildcard 0 is no longer allowed).
• Pre-T1C: chain_id == 0 is a wildcard (valid on any chain), otherwise must match.

pub fn size(&self) -> usize

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

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for SignedKeyAuthorization

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

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

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

fn clone(&self) -> SignedKeyAuthorization

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Compact for SignedKeyAuthorization

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) -> (SignedKeyAuthorization, &[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 SignedKeyAuthorization

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

Formats the value using the given formatter.

impl Decodable for SignedKeyAuthorization

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

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

impl Deref for SignedKeyAuthorization

type Target = KeyAuthorization

The resulting type after dereferencing.

fn deref(&self) -> &<SignedKeyAuthorization as Deref>::Target

Dereferences the value.

impl<'de> Deserialize<'de> for SignedKeyAuthorization

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for SignedKeyAuthorization

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 SignedKeyAuthorization

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 SignedKeyAuthorization

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

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 SignedKeyAuthorization

impl StructuralPartialEq for SignedKeyAuthorization

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.
