Struct PublicKey

pub struct PublicKey { /* private fields */ }

The public key of a node’s identity keypair.

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 encode_protobuf(&self) -> Vec<u8>

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

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

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

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.

where Self: Sized,

Compares and returns the minimum of two values.

impl PartialEq for PublicKey

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

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.
