|\ \ | |/ |/| | | | | | | | | | | | | | | | | 2466: Handle partial resolve cases r=matklad a=edwin0cheng Another try to fix #2443 : We resolve all imports every time in `DefCollector::collect` loop even it is resolved previously. This is because other unresolved imports and macros will bring in another `PerNs`, so we can only assume that it has been partially resolved. Co-authored-by: Edwin Cheng <[email protected]>

Also remove the `len` parameter from `Name::new_inline_ascii`, which I'm assuming was only there because of `const fn` limitations? cc @edwin0cheng Co-authored-by: Florian Diebold <[email protected]>

| | | | | | | | | | | | | | | | | | | | | SourceAnalyzer didn't work properly within expression macro expansions because it didn't find the enclosing function. Fix this by going up the expansion chain to find ancestors. This makes the test work, but apparently in real usage it's still not working.

* | | Don't unify within a referenceFlorian Diebold2019-12-063-11/+72
| |/ |/| | | | | | | | | | | If we are expecting a `&Foo` and get a `&something`, when checking the `something`, we are *expecting* a `Foo`, but we shouldn't try to unify whatever we get with that expectation, because it could actually be a `&Foo`, and `&&Foo` coerces to `&Foo`. So this fixes quite a few false type mismatches.

|\ \ | |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | 2479: Add expansion infrastructure for derive macros r=matklad a=flodiebold I thought I'd experiment a bit with attribute macro/derive expansion, and here's what I've got so far. It has dummy implementations of the Copy / Clone derives, to show that the approach works; it doesn't add any attribute macro support, but I think that fits into the architecture. Basically, during raw item collection, we look at the attributes and generate macro calls for them if necessary. Currently I only do this for derives, and just add the derive macro calls as separate calls next to the item. I think for derives, it's important that they don't obscure the actual item, since they can't actually change it (e.g. sending the item token tree through macro expansion unnecessarily might make completion within it more complicated). Attribute macros would have to be recognized at that stage and replace the item (i.e., the raw item collector will just emit an attribute macro call, and not the item). I think when we implement this, we should try to recognize known inert attributes, so that we don't do macro expansion unnecessarily; anything that isn't known needs to be treated as a possible attribute macro call (since the raw item collector can't resolve the macro yet). There's basically no name resolution for attribute macros implemented, I just hardcoded the built-in derives. In the future, the built-ins should work within the normal name resolution infrastructure; the problem there is that the builtin stubs in `std` use macros 2.0, which we don't support yet (and adding support is outside the scope of this). One aspect that I don't really have a solution for, but I don't know how important it is, is removing the attribute itself from its input. I'm pretty sure rustc leaves out the attribute macro from the input, but to do that, we'd have to create a completely new syntax node. I guess we could do it when / after converting to a token tree.
