const (
	Wei   = 1
	GWei  = 1e9
	Ether = 1e18

type ConfigCompatError 

type ConfigCompatError struct {
	What string
	// block numbers of the stored and new configurations
	StoredConfig, NewConfig *big.Int
	// the block number to which the local chain must be rewound to correct the error
	RewindTo uint64
}

ConfigCompatError is raised if the locally-stored blockchain is initialised with a ChainConfig that would alter the past.

func (*ConfigCompatError) Error 

func (err *ConfigCompatError) Error() string

type Rules 

type Rules struct {
	ChainID                                                 *big.Int

	IsByzantium, IsConstantinople, IsPetersburg, IsIstanbul bool
	IsBerlin, IsLondon                                      bool
}

Rules wraps ChainConfig and is merely syntactic sugar or can be used for functions that do not have or require information about the block.

Rules is a one time interface meaning that it shouldn't be used in between transition phases.
