Constants 

const CurrentVersion = 1

CurrentVersion is the current wire and protocol version. 

const HeaderStructSize = 8

HeaderStructSize size of header struct in bytes.

Types 

type Header struct {
	// HeaderSize is the size of the header in bytes. The payload comes
	// immediately after the header. The length is needed to allow the header to
	// expand in the future without breaking remotes that do not yet understand
	// the new fields.
	HeaderSize uint16

	// MessageType describes the payload. It must be one of the pb.MessageType
	// values and determine how the payload is interpreted. This is more efficient
	// than using protobuf.Any because Any uses the full protobuf name to identify
	// the type.
	MessageType uint16

	// DroppedCount is the number of points that failed to be written and had to
	// be dropped. It wraps around after max(uint32).
	DroppedCount uint32
}

Header is used to describe the message being sent to the remote process.
