Module 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.
