Struct ContractSignature 

pub struct ContractSignature(/* private fields */);

A recoverable ECDSA signature for a contract-specific digest format (ERC-191).

Implementations

impl ContractSignature

pub fn from_signature(signature: Signature) -> ContractSignature

Create a ContractSignature from a Signature.

pub fn create<T>( contract_address: Address, private_key: &PrivateKey, data: T, ) -> Result<ContractSignature, SignerError>

where Digest: From<T>,

Create a recoverable contract-specific signature for the provided data using the private key.

pub fn create_from_digest( contract_address: Address, private_key: &PrivateKey, digest: Digest, ) -> Result<ContractSignature, SignerError>

pub fn validate<T>( &self, contract_address: Address, data: T, ) -> Result<PublicKey, SignerError>

where Digest: From<T>,

pub fn into_pre_eip155_bytes(self) -> [u8; 65]

Trait Implementations

impl Copy for ContractSignature

impl Debug for ContractSignature

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

Formats the value using the given formatter.

where __CodecInputEdqy: Input,

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

where __CodecOutputEdqy: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<__CodecOutputReturn, __CodecUsingEncodedCallback>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

where __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn,

impl EncodeLike for ContractSignature

impl Eq for ContractSignature

impl Hash for ContractSignature

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 ContractSignature

fn eq(&self, other: &ContractSignature) -> 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.
