Module bus_mapping::operation

Collection of structs and functions used to:

• Define the internals of a MemoryOp, StackOp and StorageOp.
• Define the actual operation types and a wrapper over them (the Operation enum).
• Define structures that interact with operations such as OperationContainer.

Structs

• AccountOp
  Represents a change in the Account field implied by a BeginTx, EXTCODECOPY, EXTCODESIZE, BALANCE, SELFDESTRUCT, *CALL*, CREATE*, STOP, RETURN or REVERT step.
• CallContextOp
  Represents an CallContext read/write operation.
• MemoryAddress
  Represents a MemoryAddress of the EVM.
• MemoryOp
  Represents a READ/WRITE into the memory implied by an specific OpcodeId of the ExecStep.
• Operation
  Operation is a Wrapper over a type that implements Op with a RWCounter.
• OperationContainer
  The OperationContainer is meant to store all of the Operations that an ExecStep performs during its execution.
• PaddingOp
  Represent a Padding padding operation
• RWCounter
  Wrapper type over usize which represents the global counter. The purpose of the RWCounter is to enforce that each Opcode/Instruction and Operation is unique and just executed once.
• StackAddress
  Represents a StackAddress of the EVM. The address range goes TOP -> DOWN (1024, 0].
• StackOp
  Represents a READ/WRITE into the stack implied by an specific OpcodeId of the ExecStep.
• StartOp
  Represent a Start padding operation
• StepStateOp
  StepStateOp represents exec state store and load
• StorageOp
  Represents a READ/WRITE into the storage implied by a specific OpcodeId of the ExecStep.
• TargetIter
  An iterator over the variants of Self
• TransientStorageOp
  Represents a READ/WRITE into the transient storage implied by a specific OpcodeId of the ExecStep.
• TxAccessListAccountOp
  Represents a change in the Account AccessList implied by a BeginTx, EXTCODECOPY, EXTCODESIZE, EXTCODEHASH BALANCE, SELFDESTRUCT, *CALL* or CREATE* step.
• TxAccessListAccountStorageOp
  Represents a change in the Storage AccessList implied by an SSTORE or SLOAD step of the ExecStep.
• TxLogOp
  Represents TxLog read/write operation.
• TxReceiptOp
  Represents TxReceipt read/write operation.
• TxRefundOp
  Represents a change in the Transaction Refund AccessList implied by an SSTORE, STOP, RETURN or REVERT step of the ExecStep.

Enums

• AccountField
  Represents a field parameter of the Account that can be accessed via EVM execution.
• CallContextField
  Represents a field parameter of the CallContext that can be accessed via EVM execution.
• OpEnum
  Generic enum that wraps over all the operation types possible. In particular StackOp, MemoryOp and StorageOp.
• RW
  Marker that defines whether an Operation performs a READ or a WRITE.
• StepStateField
  Represents a field parameter of the StepStateField.
• Target
  Enum used to differentiate between EVM Stack, Memory and Storage operations. This is also used as the RwTableTag for the RwTable.
• TxLogField
  Represents a field parameter of the TxLog that can be accessed via EVM execution.
• TxReceiptField
  Represents a field parameter of the TxReceipt that can be accessed via EVM execution.

Traits

• Op
  Trait used for Operation Kinds.
