pub fn open_named_in_memory_mouth(name: &str, content: String) -> Result<()>Expand description
Open a gullet mouth over in-memory content whose source is named name
(a real path/filename). Uses the Mouth’s cached-content branch so locators
carry name rather than “Anonymous String”.
Low-level and position-agnostic: it does NOT touch the document-global
SOURCEDIRECTORY/SEARCHPATHS, so it is safe for a continuation (the
forked child’s body over already-inherited state) or a nested include. For
the main document load, go through Converter::digest_named, which
installs the document directory first.
