Structs§

ActionParams: Action (call/create) input params. Everything else should be specified in Externalities.
CIP645Spec: Represents the feature flags for CIP-645 implementation.
ConsensusGasSpec: Spec parameters are determined solely by block height and thus accessible to the consensus protocol.
Env: Information concerning the execution environment for a message-call/contract-creation.
ReturnData: Return data buffer. Holds memory from a previous call and a slice into that memory.
Spec: Definition of the cost spec and other parameterisations for the VM.

ActionValue: Transaction value
BlockHashSource
CallType: The type of the call-like instruction.
ContractCreateResult: Result of externalities create function.
CreateContractAddress: Specifies how an address is calculated for a new contract.
CreateType: The type of the create-like instruction.
Error: VM errors.
GasLeft: Gas Left: either it is a known value, or it needs to be computed by processing a return instruction.
InstructionResult
MessageCallResult: Result of externalities call function.
ParamsType: Type of the way parameters encoded
TrapError
TrapKind
TrapResult

contract_address: Calculate new contract address.
extract_7702_payload
separate_out_db_error: Separate out database-related errors from other EVM errors. The EVM itself does not distinguish between errors that originate from within (e.g., index out-of-bounds) and those that come from external sources like database operations.
