Types ¶
type BodyHandler ¶
type BodyHandler interface {
// IntegrityAndValidity checks the integrity and validity of the block
IntegrityAndValidity() error
// IsInterfaceNil returns true if there is no value under the interface
IsInterfaceNil() bool
}
BodyHandler interface for a block body
type CapnpHelper ¶ added in v1.0.3
type CapnpHelper interface {
// Save saves the serialized data of the implementer type into a stream through Capnp protocol
Save(w io.Writer) error
// Load loads the data from the stream into a go structure through Capnp protocol
Load(r io.Reader) error
}
CapnpHelper is an interface that defines methods needed for serializing and deserializing Capnp structures into Go structures and viceversa
type ChainHandler ¶
type ChainHandler interface {
GetGenesisHeader() HeaderHandler
SetGenesisHeader(gb HeaderHandler) error
GetGenesisHeaderHash() []byte
SetGenesisHeaderHash(hash []byte)
