Types

type Batch

type Batch struct {
	BlockIDs []flow.Identifier
}

Batch is a set of block IDs we want to request.

type Range

type Range struct {
	From uint64
	To   uint64
}

Range is a height range for which we want to request blocks. inclusive [from, to]

func (*Range) Len

func (r *Range) Len() int

type Status

type Status struct {
	BlockHeight uint64       // always present even if we haven't received the header
	Queued      time.Time    // when we originally queued this block request
	Requested   time.Time    // the last time we requested this block
	Attempts    uint         // how many times we've requested this block
	Header      *flow.Header // the requested header, if we've received it
	Received    time.Time    // when we received a response
}

Status keeps track of a block download status.
