* infer: Add type inference support for Union typesOtavio Salvador2020-07-111-2/+9
| | | | | | | | This adds the type inference to Union types and add a small test case for it, ensuring it keeps working in future. Fixes: #5277 Signed-off-by: Otavio Salvador <[email protected]>

| | | | Removes redundant clones
* Implement Chalk variable kindsFlorian Diebold2020-07-011-15/+40
| | | | | | | | | This means we need to keep track of the kinds (general/int/float) of variables in `Canonical`, which requires some more ceremony. (It also exposes some places where we're not really dealing with canonicalization correctly -- another thing to be cleaned up when we switch to using Chalk's types directly.) Should fix the last remaining issue of #2534.

* Clean up handling of int/float literal typesFlorian Diebold2020-06-061-16/+12
| | | | | | 'Unknown' int/float types actually never exist as such, they get replaced by type variables immediately. So the whole `Uncertain<IntTy>` thing was unnecessary and just led to a bunch of match branches that were never hit.
* Fix type parameter defaultsFlorian Diebold2020-06-051-1/+2
| | | | | They should not be applied in expression or pattern contexts, unless there are other explicitly given type args.

* Handle `Self` in values and patternsFlorian Diebold2020-05-151-1/+34
| | | | | | | | | I.e. - `Self(x)` or `Self` in tuple/unit struct impls - `Self::Variant(x)` or `Self::Variant` in enum impls - the same in patterns Fixes #4454.
* Handle coercing function types to function pointers in matchFlorian Diebold2020-05-081-11/+23
| | | | | | | | | | | | E.g. in ```rust match x { 1 => function1, 2 => function2, } ``` we need to try coercing both to pointers. Turns out this is a special case in rustc as well (see the link in the comment).
* Add diagnostic for break outside of loopFlorian Diebold2020-05-081-0/+4
|
* Handle break somewhat betterFlorian Diebold2020-05-081-2/+27
| | | | | Still no break-with-value or labels, but at least we know that `loop { break; }` doesn't diverge.
* Implement better handling of divergenceFlorian Diebold2020-05-081-14/+39
| | | | | | | | Divergence here means that for some reason, the end of a block will not be reached. We tried to model this just using the never type, but that doesn't work fully (e.g. in `let x = { loop {}; "foo" };` x should still have type `&str`); so this introduces a `diverges` flag that the type checker keeps track of, like rustc does.
* Fix type of byte literalsFlorian Diebold2020-05-081-2/+2
| | | | They're `&[u8; N]`, not `&[u8]` (see #4374).

| | | | | | | Fixes a lot of false type mismatches. (And as always when touching the unification code, I have to say I'm looking forward to replacing it by Chalk's...)

* Upgrade Chalk againFlorian Diebold2020-04-051-11/+17
| | | | | | | The big change here is counting binders, not variables (https://github.com/rust-lang/chalk/pull/360). We have to adapt to the same scheme for our `Ty::Bound`. It's mostly fine though, even makes some things more clear.
* Add inference for literal and range patternsFlorian Diebold2020-04-011-2/+9
|
* Use `dyn Trait` for working with databseAleksey Kladov2020-03-165-37/+35
| | | | | | | It improves compile time in `--release` mode quite a bit, it doesn't really slow things down and, conceptually, it seems closer to what we want the physical architecture to look like (we don't want to monomorphise EVERYTHING in a single leaf crate).
* Resolve `Self::AssocTy` in implsFlorian Diebold2020-03-061-2/+2
| | | | | | | | | | To do this we need to carry around the original resolution a bit, because `Self` gets resolved to the actual type immediately, but you're not allowed to write the equivalent type in a projection. (I tried just comparing the projection base type with the impl self type, but that seemed too dirty.) This is basically how rustc does it as well. Fixes #3249.
