List of evm-call-message pre-checking errors. All state transition messages will be pre-checked before execution. If any invalidation detected, the corresponding error should be returned which is defined here.

- If the pre-checking happens in the miner, then the transaction won't be packed. - If the pre-checking happens in the block processing procedure, then a "BAD BLOCk" error should be emitted.

Types

type ChainEvent

type ChainEvent struct {
	Block *types.Block
	Hash  common.Hash
	Logs  []*types.Log
}

type ChainHeadEvent

type ChainHeadEvent struct{ Block *types.Block }

type ChainSideEvent

type ChainSideEvent struct {
	Block *types.Block
}

type GasPool

type GasPool uint64

GasPool tracks the amount of gas available during execution of the transactions in a block. The zero value is a pool with zero gas available.

func (*GasPool) AddGas

func (gp *GasPool) AddGas(amount uint64) *GasPool

AddGas makes gas available for execution.

func (*GasPool) Gas

func (gp *GasPool) Gas() uint64

Gas returns the amount of gas remaining in the pool.

func (*GasPool) String

func (gp *GasPool) String() string

func (*GasPool) SubGas

func (gp *GasPool) SubGas(amount uint64) error

SubGas deducts the given amount from the pool if enough gas is available and returns an error otherwise.

type NewMinedBlockEvent

type NewMinedBlockEvent struct{ Block *types.Block }

NewMinedBlockEvent is posted when a block has been imported.

type NewTxsEvent

type NewTxsEvent struct{ Txs []*types.Transaction }

NewTxsEvent is posted when a batch of transactions enter the transaction pool.

type RemovedLogsEvent

type RemovedLogsEvent struct{ Logs []*types.Log }

RemovedLogsEvent is posted when a reorg happens
