* internal: intern `TypeBound`sJonas Schievink2021-05-241-1/+2
| | | | | Doesn't save much memory (~2 mb), but interning things is generally a good pattern to follow
* Rework obligation handlingFlorian Diebold2021-05-211-1/+3
| | | | | | | | We can't do the easy hack that we did before anymore, where we kept track of whether any inference variables changed since the last time we rechecked obligations. Instead, we store the obligations in canonicalized form; that way we can easily check the inference variables to see whether they have changed since the goal was canonicalized.
* Address final feedbackJade2021-05-161-12/+7
| | | | | * rename ConstExtension->ConstExt * refactor a manual construction of a Const
* Add lowering of array lengths in typesJade2021-05-131-10/+16
| | | | | | | | | | | Now e.g. ```rust fn a(b: [u8; 2]) { } ``` will know about the length of b.
* Add basic support for array lengths in typesJade2021-05-111-0/+2
| | | | | | | | | | This recognizes `let a = [1u8, 2, 3]` as having type `[u8; 3]` instead of the previous `[u8; _]`. Byte strings and `[0u8; 2]` kinds of range array declarations are unsupported as before. I don't know why a bunch of our rustc tests had single quotes inside strings un-escaped by `UPDATE_EXPECT=1 cargo t`, but I don't think it's bad? Maybe something in a nightly?
* Don't look in super traits for <T as Trait>::AssocFlorian Diebold2021-04-291-7/+6
| | | | | | | This isn't actually how it works, you have to specify the exact trait that has the associated type. Fixes #8686.

* Move ToChalk -> mappingFlorian Diebold2021-04-091-4/+4
|
* Reorganize hir_ty modulesFlorian Diebold2021-04-091-1/+2
| | | | | Chalk isn't really a 'traits' thing anymore, so it doesn't make sense to have all the Chalk-related stuff in submodules of `traits`.

* infer: remove `record_field_resolutions` fieldJonas Schievink2021-04-061-3/+2
| | | | | It stores no useful data, since we can derive all fields from `variant_resolutions`

|
* Fix shifting of binders in FnPointerFlorian Diebold2021-04-051-2/+3
| | | | | | | | | - 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
* Align FnPointer with ChalkFlorian Diebold2021-04-051-5/+5

* Use bitflags to compress function propertiesJonas Schievink2021-04-031-1/+1
| | | | Very minor savings, only 1 MB or so
* Introduce `GenericArg` like in ChalkFlorian Diebold2021-04-031-8/+9
| | | | | | | Plus some more adaptations to Substitution. Lots of `assert_ty_ref` that we should revisit when introducing lifetime/const parameters.
* Merge #8284bors[bot]2021-04-021-1/+1
|\ | | | | | | | | | | | | | | 8284: Reduce memory usage by using global `Arc`-based interning r=jonas-schievink a=jonas-schievink This saves around 50 mb when running `analysis-stats` on r-a itself. Not a lot, but this infra can be easily reused to intern more stuff. Co-authored-by: Jonas Schievink <[email protected]>
