builtin_program_ids: RwLock<HashSet<Pubkey>>

Builtin program ids

Implementations

impl<FG: ForkGraph> TransactionBatchProcessor<FG>

pub fn new_uninitialized(slot: Slot, epoch: Epoch) -> Self

Create a new, uninitialized TransactionBatchProcessor.

In this context, uninitialized means that the TransactionBatchProcessor has been initialized with an empty program cache. The cache contains no programs (including builtins) and has not been configured with a valid fork graph.

When using this method, it’s advisable to call set_fork_graph_in_program_cache as well as add_builtin to configure the cache before using the processor.

pub fn new_from(&self, slot: Slot, epoch: Epoch) -> Self

Create a new TransactionBatchProcessor from the current instance, but with the provided slot and epoch.

• Inherits the program cache and builtin program ids from the current instance.
• Resets the sysvar cache.

pub fn sysvar_cache(&self) -> RwLockReadGuard<'_, SysvarCache>

pub fn load_and_execute_sanitized_transactions<CB: TransactionProcessingCallback>( &self, callbacks: &CB, sanitized_txs: &[impl SVMTransaction], check_results: Vec<TransactionCheckResult>, environment: &TransactionProcessingEnvironment<'_>, config: &TransactionProcessingConfig<'_>, ) -> LoadAndExecuteSanitizedTransactionsOutput

Main entrypoint to the SVM.

pub fn prepare_program_cache_for_upcoming_feature_set<CB: TransactionProcessingCallback>( &self, callbacks: &CB, upcoming_feature_set: &FeatureSet, compute_budget: &ComputeBudget, slot_index: u64, slots_in_epoch: u64, )

pub fn fill_missing_sysvar_cache_entries<CB: TransactionProcessingCallback>( &self, callbacks: &CB, )

pub fn reset_sysvar_cache(&self)

pub fn get_sysvar_cache_for_tests(&self) -> SysvarCache

pub fn add_builtin<CB: TransactionProcessingCallback>( &self, callbacks: &CB, program_id: Pubkey, name: &str, builtin: ProgramCacheEntry, )

Add a built-in program
