Implementations

impl<Ctx: Context> Table<Ctx>

pub fn new(config: Config) -> Self

Create a new Table from a Config.

pub fn attested_candidate( &self, digest: &Ctx::Digest, context: &Ctx, minimum_backing_votes: u32, ) -> Option<AttestedCandidate<Ctx::GroupId, Ctx::Candidate, Ctx::AuthorityId, Ctx::Signature>>

Get the attested candidate for digest.

Returns Some(_) if the candidate exists and is includable.

pub fn import_statement( &mut self, context: &Ctx, group_id: Ctx::GroupId, statement: SignedStatement<Ctx::Candidate, Ctx::Digest, Ctx::AuthorityId, Ctx::Signature>, ) -> Option<Summary<Ctx::Digest, Ctx::GroupId>>

Import a signed statement. Signatures should be checked for validity, and the sender should be checked to actually be an authority.

Validity and invalidity statements are only valid if the corresponding candidate has already been imported.

If this returns None, the statement was either duplicate or invalid.

pub fn get_candidate(&self, digest: &Ctx::Digest) -> Option<&Ctx::Candidate>

Get a candidate by digest.

pub fn get_misbehavior( &self, ) -> &HashMap<Ctx::AuthorityId, Vec<MisbehaviorFor<Ctx>>>

Access all witnessed misbehavior.

pub fn drain_misbehaviors(&mut self) -> DrainMisbehaviors<'_, Ctx>

Create a draining iterator of misbehaviors.

This consumes all detected misbehaviors, even if the iterator is not completely consumed.
