Types

type AddrLocker 

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

func (*AddrLocker) LockAddr 

func (l *AddrLocker) LockAddr(address common.Address)

func (*AddrLocker) UnlockAddr 

func (l *AddrLocker) UnlockAddr(address common.Address)

UnlockAddr unlocks the mutex of the given account.
