The MIR type checker. Visits the MIR and enforces all the constraints needed for it to be valid and well-typed. Along the way, it accrues region constraints -- these can later be used by NLL region checking.

Given some operation op that manipulates types, proves predicates, or otherwise uses the inference context, executes op and then executes all the further obligations that op returns. This will yield a set of outlives constraints amongst regions which are extracted and stored as having occurred at locations.

Any rustc::infer operations that might generate region constraints should occur within this method so that those constraints can be properly localized!

Add the constraints that arise from a borrow expression &'a P at the location L.

Parameters

  • location: the location L where the borrow expression occurs
  • borrow_region: the region 'a associated with the borrow
  • borrowed_place: the place P being borrowed
