pub fn label_of_release(response: &Json) -> Option<LabelOfRelease>Expand description
The label of a release, as a release lookup returns it.
Separate from release_groups because it comes from a different request,
and because it describes an edition rather than the album.
The name and the identifier are read from the same label-info entry
— the first one that names a label — never a name from one row and an
identifier from another: a release crediting several labels would
otherwise risk pairing the name of one with the address of a different
one. This supplies edition evidence independently of any explicit label
identifier already carried by local tags.
