Expand description

Gear message processor.

Modules§

ContextChargedForCode: The instance returned by precharge_for_code. Existence of the instance means that corresponding counters were successfully charged for fetching the binary code from storage.
ContextChargedForInstrumentation: The instance returned by precharge_for_instrumentation. Existence of the instance means that corresponding counters were successfully charged for reinstrumentation of the code.
Ext: Structure providing externalities for running host functions.
ProcessExecutionContext: Checked parameters for message execution across processing runs.
ProcessorContext: Processor context.

ActorPrepareMemoryError: Prepare memory error
AllocExtError: Ext’s memory management (calls to allocate and free) error.
FallibleExtError: Fallible API error.
UnrecoverableExtError: Infallible API error.

ProcessorExternalities: Trait to which ext must have to work in processor wasm executor. Currently used only for lazy-pages support.

calculate_gas_for_code: Calculates gas amount required to charge for code loading.
calculate_gas_for_program: Calculates gas amount required to charge for program loading.
execute_wasm: Execute wasm with dispatch and return dispatch result.
handle_journal: Handle some journal records passing them to the journal handler.
precharge_for_code: Charge a message for the program binary code beforehand.
precharge_for_code_length: Charge a message for fetching the actual length of the binary code from a storage. The updated value of binary code length should be kept in standalone storage. The caller has to call this function to charge gas-counters accordingly before fetching the value.
precharge_for_instrumentation: Charge a message for instrumentation of the binary code beforehand.
precharge_for_memory: Charge a message for program memory and module instantiation beforehand.
precharge_for_program: Charge a message for program data beforehand.
process: Process program & dispatch for it and return journal for updates.
