Implementations

impl PublicKey

pub fn verify(&self, msg: &[u8], sig: &[u8]) -> bool

Verify a signature for a message using this public key, i.e. check that the signature has been produced by the corresponding private key (authenticity), and that the message has not been tampered with (integrity).

pub fn to_protobuf_encoding(&self) -> Vec<u8>

Encode the public key into a protobuf structure for storage or exchange with other nodes.

pub fn from_protobuf_encoding(bytes: &[u8]) -> Result<PublicKey, DecodingError>

Decode a public key from a protobuf structure, e.g. read from storage or received from another node.

pub fn to_peer_id(&self) -> PeerId

Convert the PublicKey into the corresponding PeerId.

Trait Implementations

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 From<&PublicKey> for PeerId

fn from(key: &PublicKey) -> PeerId

Converts to this type from the input type.

impl From<PublicKey> for PeerId

fn from(key: PublicKey) -> PeerId

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) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<PublicKey> for PublicKey

fn eq(&self, other: &PublicKey) -> 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 PartialOrd<PublicKey> for PublicKey

fn partial_cmp(&self, other: &PublicKey) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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