Implementations

impl Signature

pub fn new(v: bool, r: Uint256, s: Uint256) -> Signature

pub fn new_legacy(v: Uint256, r: Uint256, s: Uint256) -> Signature

pub fn get_r(&self) -> Uint256

pub fn get_s(&self) -> Uint256

pub fn get_v(&self) -> Uint256

Gets the v value, potentially encoded with a chain id

pub fn error_check(&self) -> Result<(), Error>

Like is_valid() but returns a reason

pub fn is_valid(&self) -> bool

pub fn legacy_network_id(&self) -> Option<Uint256>

Extracts the chain id from the legacy signature v value will return none if the signature is either a legacy signature not protected from replay or if the signature is a modern signature at which point the chain_id value is contained in the tx

pub fn get_signature_v(&self) -> Result<u8, Error>

Get the actual signature component V value, only two possibilities 27 or 28 this is different from V encoded with a chain id for which you should use get_v()

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

Converts a signature into a bytes string.

A signature in binary form consists of 65 bytes where first 32 bytes are “r” in big endian form, next 32 bytes are “s” in big endian form, and at the end there is one byte made of “v”.

This also consumes the signature.

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

Extracts signature as bytes.

This supersedes into_bytes as it does not consume the object itself.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, Error>

Constructs a signature from a bytes string

This is opposite to into_bytes() where a signature is created based on a slice of bytes.

pub fn recover(&self, hash: &[u8]) -> Result<Address, Error>

Recover an address from a signature

This can be called with any arbitrary signature, and a hashed message.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Signature

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

Formats the value using the given formatter.

impl FromStr for Signature

fn from_str(s: &str) -> Result<Self, Self::Err>

Constructs a signature back from a string representation

The input string’s length should be exactly 130 not including optional “0x” prefix at the beggining.

type Err = Error

The associated error which can be returned from parsing.

impl Hash for Signature

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 LowerHex for Signature

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

Formats the value using the given formatter.

impl PartialEq for Signature

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl UpperHex for Signature

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

Formats the value using the given formatter.

impl Eq for Signature

impl StructuralPartialEq for Signature
