impl<TYPES: NodeType> DrbComputations<TYPES>

pub fn new() -> Self

Create a new DrbComputations

async fn join_or_abort_old_task(&mut self, epoch: TYPES::Epoch) -> bool

If a task is currently live AND has finished, join it and save the result. If the epoch for the calculation was the same as the provided epoch, return true If a task is currently live and NOT finished, abort it UNLESS the task epoch is the same as cur_epoch, in which case keep letting it run and return true. Return false if a task should be spawned for the given epoch.

pub fn store_seed(&mut self, epoch: TYPES::Epoch, drb_seed_input: DrbSeedInput)

Stores a seed for a particular epoch for later use by start_task_if_not_running, called from handle_quorum_proposal_validated_drb_calculation_start

pub async fn start_task_if_not_running(&mut self, epoch: TYPES::Epoch)

Starts a new task. Cancels a current task if that task is not for the provided epoch. Allows a task to continue running if it was already started for the given epoch. Avoids running the task if we already have a result for the epoch.

pub fn get_result(&self, epoch: TYPES::Epoch) -> Option<DrbResult>

Retrieves the result for a given epoch

pub fn get_seed(&self, epoch: TYPES::Epoch) -> Option<DrbSeedInput>

Retrieves the seed for a given epoch

pub fn garbage_collect(&mut self, epoch: TYPES::Epoch)
