Struct RedPerm 

pub(crate) struct RedPerm<'db>(Id, PhantomData<&'db Value<RedPerm<'static>>>);

A “lien chain” is a list of permissions by which some data may have been reached. An empty lien chain corresponds to owned data (my, in surface Dada syntax). A lien chain like ref[p] mut[q] would correspond to data referencing a variable p which in turn had data mutable from q (which in turn owned the data).

Tuple Fields

0: Id

1: PhantomData<&'db Value<RedPerm<'static>>>
