Expand description

Implemented for Path objects that will always be able to obtain their data piece.

Such paths are those that

don’t go through any enum (if the enum is in a different variant, then the data cannot be obtained)
don’t go through Vec or HashMap (the requested item might not be in the collection)

The methods in this trait are similar to the borrow methods in PathExt, but they don’t return Option because we know the data is always there.
