示例1: FetchBlockHeaderBySha
// FetchBlockHeaderBySha - return a btcwire ShaHash
func (db *LevelDb) FetchBlockHeaderBySha(sha *btcwire.ShaHash) (bh *btcwire.BlockHeader, err error) {
db.dbLock.Lock()
defer db.dbLock.Unlock()
// Read the raw block from the database.
buf, _, err := db.fetchSha(sha)
if err != nil {
return nil, err
}
// Only deserialize the header portion and ensure the transaction count
// is zero since this is a standalone header.
var blockHeader btcwire.BlockHeader
err = blockHeader.Deserialize(bytes.NewReader(buf))
if err != nil {
return nil, err
}
bh = &blockHeader
return bh, err

// TestBlockHeaderSerialize tests BlockHeader serialize and deserialize.
