Function keyWithSymbolToHeight

sqlchain/chain.go:91–96

keyWithSymbolToHeight converts a height back from a key(ack/resp/req/block) in bytes. ack key: ['Q', 'A', 'C', 'K', height, hash] resp key: ['R', 'E', 'S', 'P', height, hash] req key: ['R', 'E', 'Q', 'U', height, hash] block key: ['B', 'L', 'C', 'K', height, hash].

(k []byte)

// block key:
// ['B', 'L', 'C', 'K', height, hash].

	if len(k) < 8 {
		return -1
	}
	return int32(binary.BigEndian.Uint32(k[4:]))
