Refactorings to borrowck region diagnostic reporting This PR is a followup to #66886 and #67404 EDIT: updated In this PR: Clean up how errors are collected from NLL: introduce `borrow_check::diagnostics::RegionErrors` to collect errors. This is later passed to `MirBorrowckCtx::report_region_errors` after the `MirBorrowckCtx` is created. This will allow us to refactor away some of the extra context structs floating around (but we don't do it in this PR). `borrow_check::region_infer` is now mostly free of diagnostic generating code. The signatures of most of the functions in `region_infer` lose somewhere between 4 and 7 arguments :) Left for future (feedback appreciated): - Merge `ErrorRegionCtx` with `MirBorrowckCtx`, as suggested by @matthewjasper in https://github.com/rust-lang/rust/pull/66886#issuecomment-559949499 - Maybe move the contents of `borrow_check::nll` into `borrow_check` and remove the `nll` submodule altogether. - Find a way to make `borrow_check::diagnostics::region_errors` less of a strange appendage to `RegionInferenceContext`. I'm not really sure how to do this yet. Ideas welcome. |
