Struct phron_finality::crypto::AuthorityVerifier

pub struct AuthorityVerifier {
    authorities: Vec<AuthorityId>,
}

Holds the public authority keys for a session allowing for verification of messages from that session.

Fields

authorities: Vec<AuthorityId>

Implementations

impl AuthorityVerifier

pub fn new(authorities: Vec<AuthorityId>) -> Self

Constructs a new authority verifier from a set of public keys.

pub fn verify(&self, msg: &[u8], sgn: &Signature, index: NodeIndex) -> bool

Verifies whether the message is correctly signed with the signature assumed to be made by a node of the given index.

pub fn node_count(&self) -> NodeCount

fn threshold(&self) -> usize

pub fn is_complete(&self, msg: &[u8], partial: &SignatureSet<Signature>) -> bool

Verifies whether the given signature set is a correct and complete multisignature of the message. Completeness requires more than 2/3 of all authorities.

Trait Implementations

impl Clone for AuthorityVerifier

fn clone(&self) -> AuthorityVerifier

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AuthorityVerifier

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

Formats the value using the given formatter.

impl PartialEq for AuthorityVerifier

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