|/ | | | | | I'd prefer getting rid of it, but it's used in the impl search and not super easy to replace there (I think ideally the impl search would do proper unification, but that's a bit more complicated).
* Remove Ty::substs{_mut}Florian Diebold2021-04-074-41/+24
| | | | | | Almost all uses actually only care about ADT substs, so it's better to be explicit. The methods were a bad abstraction anyway since they already didn't include the inner types of e.g. `TyKind::Ref` anymore.

|\ | | | | | | | | | | | | | | | | | | | | 8371: Don't use HirDisplayWrapper when displaying SourceCode r=matklad a=Veykril The issue was basically that when displaying for `DisplayTarget::SourceCode` some `hir_fmt` functions would create `HirDisplayWrapper`s which would then `fmt` these triggering the Display panic since `fmt::Display` can't fail the same way as `HirDisplay`. Simple fix is to just use `hir_fmt` directly. Should probably write that down somewhere in source, looking for a good spot to put that right now.

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | 8364: Memory usage improvements r=jonas-schievink a=alexmaco These are mostly focused on splitting up enum variants with large size differences between variants by `Box`-ing things up. In my testing this reduces the memory usage somewhere in the low percentages, even though the measurements are quite noisy. Co-authored-by: Alexandru Macovei <[email protected]>
| * | Use Box'es to reduce the size of hir_def::expr::Pat from 112 to 64 bytes on ↵Alexandru Macovei2021-04-061-2/+2
| | | | | | | | | | | | 64bit
| * | Use Box'es to reduce size of hir_def::expr::Expr from 128 to 72 bytes (on ↵Alexandru Macovei2021-04-061-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 64bit systems) Rationale: only a minority of variants used almost half the size. By keeping large members (especially in Option) behind a box the memory cost is only payed when the large variants are needed. This reduces the size Vec<Expr> needs to allocate.

* Fix shifting of binders in FnPointerFlorian Diebold2021-04-054-10/+23
| | | | | | | | | - don't shift in/out for Chalk mapping (we want to have the same binders now) - do shift in when creating the signature for a closure (though it shouldn't matter much) - do shift in when lowering a `fn()` type - correctly deal with the implied binder in TypeWalk
