Documentation

Overview

Package header defines a generalized Header type that all consensus & networking layers must provide.

If modules need access to the current block header information, like height, hash, time, or chain ID they should use the Header Service interface.

Types

type Info

type Info struct {
	Height  int64     // Height returns the height of the block
	Hash    []byte    // Hash returns the hash of the block header
	Time    time.Time // Time returns the time of the block
	AppHash []byte    // AppHash used in the current block header
	ChainID string    // ChainId returns the chain ID of the block
}

Info defines a struct that contains information about the header

func (*Info) Bytes

func (i *Info) Bytes() ([]byte, error)

Bytes encodes the Info struct into a byte slice using little-endian encoding

func (*Info) FromBytes

func (i *Info) FromBytes(bytes []byte) error

FromBytes decodes the byte slice into an Info struct using little-endian encoding

type Service

type Service interface {
	HeaderInfo(context.Context) Info
}

Service defines the interface in which you can get header information
