fn unrecognized_children(
directory: &Path,
adapters: &[&dyn Adapter],
io_context: &str,
) -> Result<usize>Expand description
The number of child directories of a listed profile directory that are not known agent ids: each one
is an unrecognized entry and the caller’s ignored grows by one per child. A child file is never
counted — only child directories can be unrecognized — and a child entry whose name starts with .
is skipped without counting, mirroring the profiles-directory rule: the same OS litter (*.swp,
.DS_Store) must behave the same one level deeper.
