Implementations

impl Signature

pub fn from_parts(
    signature_type: KeyType,
    signature_data: &[u8]
) -> Result<Self, ParseSignatureError>

Construct Signature from key type and raw signature blob

pub fn verify(&self, data: &[u8], public_key: &PublicKey) -> bool

Verifies that this signature is indeed signs the data with given public key. Also if public key doesn’t match on the curve returns false.

pub fn key_type(&self) -> KeyType

impl Signature

pub fn empty(key_type: KeyType) -> Self

Empty signature that doesn’t correspond to anything.

Trait Implementations

impl BorshDeserialize for Signature

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

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

Deserialize this instance from a slice of bytes.

pub fn is_u8() -> bool

Whether Self is u8. NOTE: Vec<u8> is the most common use-case for serialization and deserialization, it’s worth handling it as a special case to improve performance. It’s a workaround for specific Vec<u8> implementation versus generic Vec<T> implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details.

impl BorshSerialize for Signature

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

pub fn try_to_vec(&self) -> Result<Vec<u8, Global>, Error>

Serialize this instance into a vector of bytes.

pub fn is_u8() -> bool

Whether Self is u8. NOTE: Vec<u8> is the most common use-case for serialization and deserialization, it’s worth handling it as a special case to improve performance. It’s a workaround for specific Vec<u8> implementation versus generic Vec<T> implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details.

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl Default for Signature

fn default() -> Self

Returns the “default value” for a type.

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

fn deserialize<D>(
    deserializer: D
) -> Result<Self, <D as Deserializer<'de>>::Error> where
    D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

Formats the value using the given formatter.

impl Eq for Signature

impl PartialEq<Signature> 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: &Signature) -> bool

This method tests for !=.

impl Serialize for Signature

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 StructuralEq for Signature

impl StructuralPartialEq for Signature

impl TryFrom<&'_ str> for Signature

type Error = Box<dyn Error>

The type returned in the event of a conversion error.

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

Performs the conversion.

impl TryFrom<String> for Signature

type Error = Box<dyn Error>

The type returned in the event of a conversion error.

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

Performs the conversion.
