Function TruncateID

daemon/internal/stringid/stringid.go:26–34

TruncateID returns a shorthand version of a string identifier for presentation. For convenience, it accepts both digests ("sha256:xxxx") and IDs without an algorithm prefix. It truncates the algorithm (if any) before truncating the ID. The length of the truncated ID is currently fixed, but users sho

(id string)

// which case an "ambiguous result" error is produced. In case of a collision,
// the caller should try with a longer prefix or the full-length ID.
func TruncateID(id string) string {
	if i := strings.IndexRune(id, ':'); i >= 0 {
		id = id[i+1:]
	}
	if len(id) > shortLen {
		id = id[:shortLen]
	}
	return id
}

// GenerateRandomID returns a unique, 64-character ID consisting of a-z, 0-9.
// It guarantees that the ID, when truncated ([TruncateID]) does not consist
