pub fn note(uri: &str, docname: &str, srcdir: &Path) -> Option<PathBuf>Expand description
env.note_dependency(filename): the absolute path a uri seen in
docname refers to, or None when the uri names no local file.
Skipped, exactly as ImageCollector.process_doc skips them: data:
URIs (the image is inline), anything with a scheme (http://…), and
candidate patterns (see the module note).
