Module compute_budget_processor

Structs

ComputeBudgetLimits

Constants

DEFAULT_HEAP_COST

Roughly 0.5us/page, where page is 32K; given roughly 15CU/us, the default heap page cost = 0.5 * 15 ~= 8CU/page

DEFAULT_INSTRUCTION_COMPUTE_UNIT_LIMIT

MAX_COMPUTE_UNIT_LIMIT

MAX_HEAP_FRAME_BYTES

MAX_LOADED_ACCOUNTS_DATA_SIZE_BYTES

The total accounts data a transaction can load is limited to 64MiB to not break anyone in Mainnet-beta today. It can be set by set_loaded_accounts_data_size_limit instruction

MIN_HEAP_FRAME_BYTES

Functions

process_compute_budget_instructions

Processing compute_budget could be part of tx sanitizing, failed to process these instructions will drop the transaction eventually without execution, may as well fail it early. If succeeded, the transaction’s specific limits/requests (could be default) are retrieved and returned,
