Struct Signature

pub struct Signature {
    pub r: U256,
    pub s: U256,
    pub v: U256,
    pub y_parity: Option<Parity>,
}

Container type for all signature fields in RPC

Fields

r: U256

The R field of the signature; the point on the curve.

s: U256

The S field of the signature; the point on the curve.

v: U256

For EIP-155, EIP-2930 and Blob transactions this is set to the parity (0 for even, 1 for odd) of the y-value of the secp256k1 signature.

For legacy transactions, this is the recovery id

y_parity: Option<Parity>

The y parity of the signature. This is only used for typed (non-legacy) transactions.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for Signature

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.

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 Default for Signature

fn default() -> Signature

Returns the “default value” for a type.

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 From<Signature> for Signature

fn from(signature: Signature) -> Self

Converts to this type from the input type.

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 PartialEq for Signature

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Signature> for Signature

type Error = SignatureError

The type returned in the event of a conversion error.

fn try_from(value: Signature) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Signature

impl Eq for Signature

impl StructuralPartialEq for Signature
