Module polkadot_primitives::v8::executor_params

Abstract execution environment parameter set.

Parameter set is encoded as an opaque vector which structure depends on the execution environment itself (except for environment type/version which is always represented by the first element of the vector). Decoding to a usable semantics structure is done in polkadot-node-core-pvf.

Structs

• ExecutorParams
  Deterministically serialized execution environment semantics
• ExecutorParamsHash
  Unit type wrapper around Hash that represents an execution parameter set hash.
• ExecutorParamsPrepHash
  Unit type wrapper around Hash that represents a hash of preparation-related executor parameters.

Enums

• ExecutorParam
  The different executor parameters for changing the execution environment semantics.
• ExecutorParamError
  Possible inconsistencies of executor params.

Constants

• DEFAULT_APPROVAL_EXECUTION_TIMEOUT
  Default PVF execution timeout for approval or disputes.
• DEFAULT_BACKING_EXECUTION_TIMEOUT
  Default PVF execution timeout for backing.
• DEFAULT_LENIENT_PREPARATION_TIMEOUT
  Default PVF preparation timeout for execution requests.
• DEFAULT_LOGICAL_STACK_MAX
  Default maximum number of wasm values allowed for the stack during execution of a PVF.
• DEFAULT_NATIVE_STACK_MAX
  Default maximum number of bytes devoted for the stack during execution of a PVF.
• DEFAULT_PRECHECK_PREPARATION_TIMEOUT
  Default PVF preparation timeout for prechecking requests.
• LOGICAL_MAX_HI
  The upper bound of ExecutorParam::StackLogicalMax.
• LOGICAL_MAX_LO
  The lower bound of ExecutorParam::StackLogicalMax.
• MEMORY_PAGES_MAX
  The limit of ExecutorParam::MaxMemoryPages.
• PRECHECK_MEM_MAX_HI
