Constants ¶
const ( EthPendingBlockNumber = BlockNumber(-2) EthLatestBlockNumber = BlockNumber(-1) EthEarliestBlockNumber = BlockNumber(0) )
const ( BlockParamEarliest = "earliest" BlockParamLatest = "latest" BlockParamFinalized = "finalized" BlockParamSafe = "safe" BlockParamPending = "pending" )
const ExceedBlockGasLimitError = "out of gas in location: block gas meter; gasWanted:"
ExceedBlockGasLimitError defines the error message when txs execution exceeds the block gas limit. The txs fee is deducted in ante handler, so it shouldn't be ignored in JSON-RPC API.

}
AddrLocker is a mutex structure used to avoid querying outdated account data
func (*AddrLocker) LockAddr ¶
func (l *AddrLocker) LockAddr(address common.Address)

UnmarshalJSON parses the given JSON fragment into a BlockNumber. It supports: - "latest", "finalized", "earliest" or "pending" as string arguments - the block number Returned errors: - an invalid block number error when the given argument isn't a known strings - an out of range error when the given block number is either too little or too large

func (bnh *BlockNumberOrHash) UnmarshalJSON(data []byte) error
type EventFormat ¶
type EventFormat int
EventFormat is the format version of the events.
To fix the issue of txs exceeds block gas limit, we changed the event format in a breaking way. But to avoid forcing clients to re-sync from scatch, we make json-rpc logic to be compatible with both formats.
type FeeHistoryResult ¶
type NetworkingStack ¶
type NetworkingStack interface { // IsExtRPCEnabled returns true if the networking stack is configured to expose JSON-RPC APIs. ExtRPCEnabled() bool // RegisterHandler manually registers a new handler into the networking stack.
