Struct LoadedProgramsForTxBatch

pub struct LoadedProgramsForTxBatch {
    pub environments: ProgramRuntimeEnvironments,
    /* private fields */
}

Local view into LoadedPrograms which was extracted for a specific TX batch.

This isolation enables the global LoadedPrograms to continue to evolve (e.g. evictions), while the TX batch is guaranteed it will continue to find all the programs it requires. For program management instructions this also buffers them before they are merged back into the global LoadedPrograms.

Fields

environments: ProgramRuntimeEnvironments

Implementations

impl LoadedProgramsForTxBatch

pub fn new(slot: Slot, environments: ProgramRuntimeEnvironments) -> Self

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 duplicate 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.
