Fields

environments: ProgramRuntimeEnvironments

upcoming_environments: Option<ProgramRuntimeEnvironments>

Anticipated replacement for environments at the next epoch.

This is None during most of an epoch, and only Some around the boundaries (at the end and beginning of an epoch). More precisely, it starts with the recompilation phase a few hundred slots before the epoch boundary, and it ends with the first rerooting after the epoch boundary. Needed when a program is deployed at the last slot of an epoch, becomes effective in the next epoch. So needs to be compiled with the environment for the next epoch.

latest_root_epoch: Epoch

The epoch of the last rerooting

hit_max_limit: bool

Implementations

impl LoadedProgramsForTxBatch

pub fn new( slot: Slot, environments: ProgramRuntimeEnvironments, upcoming_environments: Option<ProgramRuntimeEnvironments>, latest_root_epoch: Epoch ) -> Self

pub fn new_from_cache<FG: ForkGraph>( slot: Slot, epoch: Epoch, cache: &LoadedPrograms<FG> ) -> Self

pub fn get_environments_for_epoch( &self, epoch: Epoch ) -> &ProgramRuntimeEnvironments

Returns the current environments depending on the given epoch

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, and transaction processing (for program management instructions). It replaces the existing entry (if any) with the provided entry. The return value contains true if an entry existed. The function also returns the newly inserted value.

pub fn find(&self, key: &Pubkey) -> Option<Arc<LoadedProgram>>

pub fn slot(&self) -> Slot

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

pub fn merge(&mut self, other: &Self)

Trait Implementations

impl Clone for LoadedProgramsForTxBatch

fn clone(&self) -> LoadedProgramsForTxBatch

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LoadedProgramsForTxBatch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LoadedProgramsForTxBatch

fn default() -> LoadedProgramsForTxBatch

Returns the “default value” for a type.
