Types

type Addresses

type Addresses []common.Address

func (Addresses) Len

func (a Addresses) Len() int

func (Addresses) Less

func (a Addresses) Less(i, j int) bool

func (Addresses) Swap

func (a Addresses) Swap(i, j int)

type Chain

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

Chain is a lightweight blockchain-like store, based on hivechain output files. This mostly exists to provide some convenient accessors for the chain.

func NewChain

func NewChain(dir string) (*Chain, error)

NewChain takes the given chain.rlp file, decodes it, and returns the blocks from the file.

func (*Chain) Balance

func (c *Chain) Balance(addr common.Address) *big.Int

Balance returns the balance of an account at the head of the chain.

func (*Chain) BlockWithTransactions

func (c *Chain) BlockWithTransactions(matchdesc string, match func(int, *types.Transaction) bool) *types.Block

BlockWithTransactions returns a block that has a matching transaction.

func (*Chain) Config

func (c *Chain) Config() *params.ChainConfig

func (*Chain) FindTransaction

func (c *Chain) FindTransaction(matchdesc string, match func(int, *types.Transaction) bool) (m *types.Transaction)

FindTransaction returns a matching transaction.

func (*Chain) GetBlock

func (c *Chain) GetBlock(number int) *types.Block

GetBlock returns the block at the specified number.

func (*Chain) GetSender

func (c *Chain) GetSender(idx int) (common.Address, uint64)

GetSender returns the address associated with account at the index in the pre-funded accounts list.

func (*Chain) Head

func (c *Chain) Head() *types.Block

Head returns the chain head.

func (*Chain) IncNonce

func (c *Chain) IncNonce(addr common.Address, amt uint64)

IncNonce increases the specified signing account's pending nonce.

func (*Chain) MustSignTx

func (c *Chain) MustSignTx(from common.Address, txdata types.TxData) *types.Transaction

SignTx signs a transaction for the specified from account, so long as that account was in the hivechain accounts dump.

func (*Chain) Storage

func (c *Chain) Storage(addr common.Address, slot common.Hash) []byte

Balance returns the balance of an account at the head of the chain.
