Implementations

impl LoadedPrograms

pub fn replenish( &mut self, key: Pubkey, entry: Arc<LoadedProgram> ) -> (bool, Arc<LoadedProgram>)

Refill the cache with a single entry. It’s typically called during transaction loading, when the cache doesn’t contain the entry corresponding to program key. The function dedupes the cache, in case some other thread replenished the entry in parallel.

pub fn assign_program( &mut self, key: Pubkey, entry: Arc<LoadedProgram> ) -> Arc<LoadedProgram>

Assign the program entry to the given key in the cache. This is typically called when a deployed program is managed (un-/re-/deployed) via loader instructions. Because of the cooldown, entires can not have the same deployment_slot and effective_slot.

pub fn prune_feature_set_transition(&mut self)

On the epoch boundary this removes all programs of the outdated feature set

pub fn prune_by_deployment_slot(&mut self, slot: Slot)

pub fn prune<F: ForkGraph>(&mut self, fork_graph: &F, new_root: Slot)

Before rerooting the blockstore this removes all programs of orphan forks

pub fn extract<S: WorkingSlot>( &self, working_slot: &S, keys: impl Iterator<Item = (Pubkey, (LoadedProgramMatchCriteria, u64))> ) -> (LoadedProgramsForTxBatch, Vec<(Pubkey, u64)>)

Extracts a subset of the programs relevant to a transaction batch and returns which program accounts the accounts DB needs to load.

pub fn merge(&mut self, tx_batch_cache: &LoadedProgramsForTxBatch)

pub fn sort_and_unload(&mut self, shrink_to: PercentageInteger)

Unloads programs which were used infrequently

pub fn remove_programs(&mut self, keys: impl Iterator<Item = Pubkey>)

Removes all the entries at the given keys, if they exist

pub fn unload_all_programs(&mut self)
