Types

type AccountAccess

type AccountAccess struct {
	Address        [20]byte                `ssz-size:"20"`    // 20-byte Ethereum address
	StorageWrites  []encodingSlotWrites    `ssz-max:"300000"` // Storage changes (slot -> [tx_index -> new_value])
	StorageReads   [][32]byte              `ssz-max:"300000"` // Read-only storage keys
	BalanceChanges []encodingBalanceChange `ssz-max:"300000"` // Balance changes ([tx_index -> post_balance])
	NonceChanges   []encodingAccountNonce  `ssz-max:"300000"` // Nonce changes ([tx_index -> new_nonce])
	Code           []CodeChange            `ssz-max:"1"`      // Code changes ([tx_index -> new_code])
}

AccountAccess is the encoding format of ConstructionAccountAccess.

func (*AccountAccess) Copy

func (e *AccountAccess) Copy() AccountAccess

Copy returns a deep copy of the account access

type BlockAccessList

type BlockAccessList struct {
	Accesses []AccountAccess `ssz-max:"300000"`
}

BlockAccessList is the encoding format of ConstructionBlockAccessList.

func (*BlockAccessList) Copy

func (e *BlockAccessList) Copy() (res BlockAccessList)

Copy returns a deep copy of the access list

func (*BlockAccessList) DecodeRLP

func (obj *BlockAccessList) DecodeRLP(dec *rlp.Stream) error

func (*BlockAccessList) EncodeRLP

func (obj *BlockAccessList) EncodeRLP(_w io.Writer) error

func (*BlockAccessList) Hash

func (e *BlockAccessList) Hash() common.Hash

Hash computes the keccak256 hash of the access list

func (*BlockAccessList) PrettyPrint

func (e *BlockAccessList) PrettyPrint() string

func (*BlockAccessList) Validate

func (e *BlockAccessList) Validate() error

Validate returns an error if the contents of the access list are not ordered according to the spec or any code changes are contained which exceed protocol max code size.

type CodeChange

type CodeChange struct {
	TxIndex uint16
	Code    []byte `json:"code,omitempty"`
}

CodeChange contains the runtime bytecode deployed at an address and the transaction index where the deployment took place.

type ConstructionAccountAccess

type ConstructionAccountAccess struct {
	// StorageWrites is the post-state values of an account's storage slots
	// that were modified in a block, keyed by the slot key and the tx index
	// where the modification occurred.
	StorageWrites map[common.Hash]map[uint16]common.Hash `json:"storageWrites,omitempty"`

	// StorageReads is the set of slot keys that were accessed during block
	// execution.
	//
	// Storage slots which are both read and written (with changed values)
	// appear only in StorageWrites.
	StorageReads map[common.Hash]struct{} `json:"storageReads,omitempty"`

	// BalanceChanges contains the post-transaction balances of an account,
	// keyed by transaction indices where it was changed.
	BalanceChanges map[uint16]*uint256.Int `json:"balanceChanges,omitempty"`

	// NonceChanges contains the post-state nonce values of an account keyed
	// by tx index.
	NonceChanges map[uint16]uint64 `json:"nonceChanges,omitempty"`

	// CodeChange is only set for contract accounts which were deployed in
	// the block.
	CodeChange *CodeChange `json:"codeChange,omitempty"`
}

ConstructionAccountAccess contains post-block account state for mutations as well as all storage keys that were read during execution. It is used when building block access list during execution.

func NewConstructionAccountAccess

func NewConstructionAccountAccess() *ConstructionAccountAccess

NewConstructionAccountAccess initializes the account access object.

type ConstructionBlockAccessList

type ConstructionBlockAccessList struct {
	Accounts map[common.Address]*ConstructionAccountAccess
}

ConstructionBlockAccessList contains post-block modified state and some state accessed in execution (account addresses and storage keys).

func NewConstructionBlockAccessList

func NewConstructionBlockAccessList() ConstructionBlockAccessList

NewConstructionBlockAccessList instantiates an empty access list.

func (*ConstructionBlockAccessList) AccountRead

func (b *ConstructionBlockAccessList) AccountRead(addr common.Address)

AccountRead records the address of an account that has been read during execution.

func (*ConstructionBlockAccessList) BalanceChange

func (b *ConstructionBlockAccessList) BalanceChange(txIdx uint16, address common.Address, balance *uint256.Int)

BalanceChange records the post-transaction balance of an account whose balance changed.

func (*ConstructionBlockAccessList) CodeChange

func (b *ConstructionBlockAccessList) CodeChange(address common.Address, txIndex uint16, code []byte)

CodeChange records the code of a newly-created contract.

func (*ConstructionBlockAccessList) Copy

func (b *ConstructionBlockAccessList) Copy() *ConstructionBlockAccessList

Copy returns a deep copy of the access list.

func (*ConstructionBlockAccessList) EncodeRLP

func (b *ConstructionBlockAccessList) EncodeRLP(wr io.Writer) error

EncodeRLP returns the RLP-encoded access list

func (*ConstructionBlockAccessList) NonceChange

func (b *ConstructionBlockAccessList) NonceChange(address common.Address, txIdx uint16, postNonce uint64)

NonceChange records tx post-state nonce of any contract-like accounts whose nonce was incremented.

func (*ConstructionBlockAccessList) PrettyPrint

func (b *ConstructionBlockAccessList) PrettyPrint() string

PrettyPrint returns a human-readable representation of the access list

func (*ConstructionBlockAccessList) StorageRead

func (b *ConstructionBlockAccessList) StorageRead(address common.Address, key common.Hash)
