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_reader<R: Read>(rd: &mut R) -> Result<Self>

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.

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

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for Signature

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

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<(), 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 FromStr for Signature

type Err = ParseSignatureError

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this 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

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 as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Signature

impl StructuralPartialEq for Signature
