pub fn open_rooted_source(path: &Path, root: &Path) -> Result<File, Error>Expand description
The rooted no-follow open on its own, for a source that is not read as
text (a history database, core::import::database): one open, relative to
the root’s descriptor, no link followed in any component on Unix, a regular
file. The caller has made the path decision and runs every further check
on the returned descriptor.
