Struct ProgramCacheForTxBatch

👎Deprecated since 3.1.0: This crate has been marked for formal inclusion in the Agave Unstable API. From v4.0.0 onward, the agave-unstable-api crate feature must be specified to acknowledge use of an interface that may break without warning.

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

This isolation enables the global ProgramCache 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 ProgramCache.

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 store_modified_entry( &mut self, key: Pubkey, entry: Arc<ProgramCacheEntry>, )

👎Deprecated since 3.1.0: This crate has been marked for formal inclusion in the Agave Unstable API. From v4.0.0 onward, the agave-unstable-api crate feature must be specified to acknowledge use of an interface that may break without warning.

Store an entry in modified_entries for a program modified during the transaction batch.

pub fn drain_modified_entries( &mut self, ) -> HashMap<Pubkey, Arc<ProgramCacheEntry>>

Drain the program cache’s modified entries, returning the owned collection.
