Crate gear_core_processor

Gear message processor.

Modules

• common
  Common structures for processing.
• configs
  Configurations.
• informational
  Informational functions for core-processor and executor.

Structs

• 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.
• ContextChargedForProgram
  Struct with dispatch and counters charged for program data.
• Ext
  Structure providing externalities for running host functions.
• ProcessExecutionContext
  Checked parameters for message execution across processing runs.
• ProcessorContext
  Processor context.
• SystemReservationContext
  System reservation context.

Enums

• AllocExtError
  Ext’s memory management (calls to allocate and free) error.
• FallibleExtError
  Fallible API error.
• SuccessfulDispatchResultKind
  Possible variants of the DispatchResult if the latter contains value.
• UnrecoverableExtError
  Infallible API error.

Traits

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

Functions

• handle_journal
  Handle some journal records passing them to the journal handler.
• precharge_for_allocations
  Precharge for allocations obtaining from storage.
• 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_module_instantiation
  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.
• process_execution_error
  Helper function for journal creation in trap/error case.
• process_non_executable
  Helper function for journal creation in message no execution case.
• process_reinstrumentation_error
  Helper function for journal creation in case of re-instrumentation error.
• process_success
  Helper function for journal creation in success case
