Functions

func EncodeAddressValue 

func EncodeAddressValue(value any, offset uint) (common.Hash, error)

EncodeAddressValue will encode an address like value given a storage offset.

func EncodeBoolValue 

func EncodeBoolValue(value any, offset uint) (common.Hash, error)

EncodeBoolValue will encode a boolean value given a storage offset.

func EncodeBytes32Value 

func EncodeBytes32Value(value any, offset uint) (common.Hash, error)

EncodeBytes32Value will encode a bytes32 value. The offset is included so that it can implement the ElementEncoder interface, but the offset must always be 0.

func EncodeStringValue 

func EncodeStringValue(value any, offset uint) (common.Hash, error)

EncodeStringValue will encode a string to a type suitable for storage in state. The offset must be 0.

func EncodeUintValue 

func EncodeUintValue(value any, offset uint) (common.Hash, error)

EncodeUintValue will encode a uint value given a storage offset

func SetStorage 

func SetStorage(name string, address common.Address, values StorageValues, db vm.StateDB) error

SetStorage will set the storage values in a db given a contract name, address and the storage values

Types

type ElementEncoder 

type ElementEncoder func(value any, offset uint) (common.Hash, error)

ElementEncoder is a function that can encode an element based on a solidity type

type EncodedStorage 

type EncodedStorage struct {
	Key   common.Hash
	Value common.Hash
}

EncodedStorage represents the storage key and value serialized to be placed in Ethereum state.

func ComputeStorageSlots 

func ComputeStorageSlots(layout *solc.StorageLayout, values StorageValues) ([]*EncodedStorage, error)

ComputeStorageSlots will compute the storage slots for a given contract.

func EncodeStorage 

func EncodeStorage(entry solc.StorageLayoutEntry, value any, storageType solc.StorageLayoutType) ([]*EncodedStorage, error)

EncodeStorage will encode a storage layout

func EncodeStorageKeyValue 

func EncodeStorageKeyValue(value any, entry solc.StorageLayoutEntry, storageType solc.StorageLayoutType) ([]*EncodedStorage, error)

EncodeStorageKeyValue encodes the key value pair that is stored in state given a StorageLayoutEntry and StorageLayoutType. A single input may result in multiple outputs. Unknown or unimplemented types will return an error. Note that encoding uints is *not* overflow safe, so be sure to check the ABI before setting very large values

func MergeStorage 

func MergeStorage(storage []*EncodedStorage) []*EncodedStorage

MergeStorage will combine any overlapping storage slots for when values are tightly packed. Do this by checking to see if any of the produced storage slots have a matching key, if so use a binary or to add the storage values together

type MemoryStateDB 

type MemoryStateDB struct {
	// contains filtered or unexported fields
}

MemoryStateDB implements geth's StateDB interface but operates on a core.Genesis so that a genesis.json can easily be created.

func NewMemoryStateDB 

func NewMemoryStateDB(genesis *core.Genesis) *MemoryStateDB

func (*MemoryStateDB) AddAddressToAccessList 

func (db *MemoryStateDB) AddAddressToAccessList(addr common.Address)

AddAddressToAccessList adds the given address to the access list. This operation is safe to perform even if the feature/fork is not active yet

func (*MemoryStateDB) AddBalance 

func (db *MemoryStateDB) AddBalance(addr common.Address, amount *big.Int)

func (*MemoryStateDB) AddLog 

func (db *MemoryStateDB) AddLog(*types.Log)

func (*MemoryStateDB) AddPreimage 

func (db *MemoryStateDB) AddPreimage(common.Hash, []byte)

func (*MemoryStateDB) AddRefund 

func (db *MemoryStateDB) AddRefund(uint64)

func (*MemoryStateDB) AddSlotToAccessList 

func (db *MemoryStateDB) AddSlotToAccessList(addr common.Address, slot common.Hash)

AddSlotToAccessList adds the given (address,slot) to the access list. This operation is safe to perform even if the feature/fork is not active yet

func (*MemoryStateDB) AddressInAccessList 

func (db *MemoryStateDB) AddressInAccessList(addr common.Address) bool

func (*MemoryStateDB) CreateAccount 

func (db *MemoryStateDB) CreateAccount(addr common.Address)

func (*MemoryStateDB) Empty 

func (db *MemoryStateDB) Empty(addr common.Address) bool

Empty returns whether the given account is empty. Empty is defined according to EIP161 (balance = nonce = code = 0).

func (*MemoryStateDB) Exist 

func (db *MemoryStateDB) Exist(addr common.Address) bool

Exist reports whether the given account exists in state. Notably this should also return true for suicided accounts.

func (*MemoryStateDB) ForEachStorage 

func (db *MemoryStateDB) ForEachStorage(addr common.Address, cb func(common.Hash, common.Hash) bool) error
