Method MakePartSet

types/block.go:140–156

MakePartSet returns a PartSet containing parts of a serialized block. This is the form in which the block is gossipped to peers. CONTRACT: partSize is greater than zero.

(partSize uint32)

// This is the form in which the block is gossipped to peers.
// CONTRACT: partSize is greater than zero.
func (b *Block) MakePartSet(partSize uint32) *PartSet {
	if b == nil {
		return nil
	}
	b.mtx.Lock()
	defer b.mtx.Unlock()

	pbb, err := b.ToProto()
	if err != nil {
		panic(err)
	}
	bz, err := proto.Marshal(pbb)
	if err != nil {
		panic(err)
	}
	return NewPartSetFromData(bz, partSize)
}

// HashesTo is a convenience function that checks if a block hashes to the given argument.
// Returns false if the block is nil or the hash is empty.
