pub fn only_borrowers( &mut self, borrowers: &[Local], borrowed: Local, at: Location, ) -> bool
Returns true if the set of borrowers of borrowed living at at matches with borrowers.

&mut self,
below: &[Local],
above: &[Local],
borrowed: Local,
at: Location,
) -> bool
pub fn bounded_borrowers( &mut self, below: &[Local], above: &[Local], borrowed: Local, at: Location, ) -> bool
Returns true if the set of borrowers of borrowed living at at includes at least below
but no more than above.
