Implementations

impl PublicKey

pub fn key_type(&self) -> &str

Return the key type as string.

pub fn as_bytes(&self) -> &[u8]

Return a byte representation of this public key.

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

Construct a public key from a slice of bytes.

pub fn verify( &self, context: &[u8], message: &[u8], signature: &Signature, ) -> Result<(), Error>

Verify a signature.

pub fn verify_raw( &self, message: &[u8], signature: &Signature, ) -> Result<(), Error>

Verify signature raw using the underlying method, without the domain separation schema.

pub fn verify_by_type( &self, signature_type: SignatureType, context_or_hash: &[u8], message: &[u8], signature: &Signature, ) -> Result<(), Error>

Verify the signature of a message.

pub fn verify_batch_multisig( context: &[u8], message: &[u8], public_keys: &[PublicKey], signatures: &[Signature], ) -> Result<(), Error>

Verify a batch of signatures of the same message.

Trait Implementations

impl AsRef<[u8]> for PublicKey

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKey

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

Formats the value using the given formatter.

impl Decode for PublicKey

fn try_from_cbor_value(value: Value) -> Result<Self, DecodeError>

Try to decode from a given CBOR value.

fn try_default() -> Result<Self, DecodeError>

where Self: Sized,

Try to decode from a missing/null/undefined value.

fn try_from_cbor_value_default(value: Value) -> Result<Self, DecodeError>

where Self: Sized,

Try to decode from a given CBOR value, calling try_default in case the value is null or undefined.

impl Encode for PublicKey

fn into_cbor_value(self) -> Value

Encode the type into a CBOR Value.

fn is_empty(&self) -> bool

Whether the value is equal to the empty value for the type.

impl EncodeAsMap for PublicKey

fn into_cbor_value_map(self) -> Value

where Self: Sized,

Encode the type into a CBOR Map.

fn into_cbor_map(self) -> Vec<(Value, Value)>

where Self: Sized,

impl From<PublicKey> for PublicKey

fn from(pk: CorePublicKey) -> Self

Converts to this type from the input type.

impl Hash for PublicKey

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 Ord for PublicKey

fn cmp(&self, other: &PublicKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq<PublicKey> for PublicKey

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

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<PublicKey> for PublicKey

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(pk: PublicKey) -> Result<Self, Self::Error>

Performs the conversion.
