Expand description

Context for the statement table.

Required Associated Types§

source

type AuthorityId: Debug + Hash + Eq + Clone

An authority ID

source

type Digest: Debug + Hash + Eq + Clone

The digest (hash or other unique attribute) of a candidate.

source

type GroupId: Debug + Hash + Ord + Eq + Clone

The group ID type

source

type Signature: Debug + Eq + Clone

A signature type.

source

type Candidate: Debug + Ord + Eq + Clone

Candidate type. In practice this will be a candidate receipt.

Required Methods§

source

fn candidate_digest(candidate: &Self::Candidate) -> Self::Digest

get the digest of a candidate.

source

fn is_member_of( &self, authority: &Self::AuthorityId, group: &Self::GroupId, ) -> bool

Whether a authority is a member of a group. Members are meant to submit candidates and vote on validity.

source

fn get_group_size(&self, group: &Self::GroupId) -> Option<usize>

Get a validator group size.

Object Safety§

This trait is not object safe.
