pub fn cover_in(folder: &Path) -> Option<PathBuf>Expand description
The image already serving as cover art in a folder, if there is one.
Reads the folder rather than the catalog, and shares its list of cover names with the scanner so that “does this album have a cover” has one answer in this program rather than two that drift. Used before anything writes an image beside music: the catalog is a snapshot and the disk is not.
