Method Hash

script.go:665–675

Hash returns the hex-encoded hash of the entire contents of the pipe based on the provided hasher, or an error. To perform hashing on files, see [Pipe.HashSums].

(hasher hash.Hash)

// pipe based on the provided hasher, or an error.
// To perform hashing on files, see [Pipe.HashSums].
func (p *Pipe) Hash(hasher hash.Hash) (string, error) {
	if p.Error() != nil {
		return "", p.Error()
	}
	_, err := io.Copy(hasher, p)
	if err != nil {
		p.SetError(err)
		return "", err
	}
	return hex.EncodeToString(hasher.Sum(nil)), nil
}

// HashSums reads paths from the pipe, one per line, and produces the
// hex-encoded hash of each corresponding file based on the provided hasher,
