API for Session Validator Management Queries

Required Methods

fn get_epoch_committee( &self, epoch_number: u64, ) -> QueryResult<GetCommitteeResponse>

Returns the committee for given sidechain epoch. The order of the list represents the order of slot allocation.

fn get_registrations<'life0, 'async_trait>( &'life0 self, mc_epoch_number: McEpochNumber, stake_pool_public_key: StakePoolPublicKey, ) -> Pin<Box<dyn Future<Output = QueryResult<Vec<CandidateRegistrationEntry>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

returns: Last active and valid registration followed by all newer invalid registrations for mc_epoch_number and stake_pool_public_key. Regardless of mc_epoch_number value, it always uses validation api from the latest sidechain block.

fn get_ariadne_parameters<'life0, 'async_trait>( &'life0 self, epoch_number: McEpochNumber, ) -> Pin<Box<dyn Future<Output = QueryResult<AriadneParameters>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Regardless of epoch_number value, all the candidates data validation is done based on the validation api from the latest sidechain block.
