Fixes #49690

Nice, thanks @wesleywiser! I'll take a look as soon as I find the time.

michaelwoerister · 2018-04-16T14:20:54Z

Looks great, @wesleywiser! Two things I'm wondering:

Does this code also need to handle statics?
Could the schema::Entry::ast field be removed entirely?

Is this expected to gain more fields? If no, how about making t a newtype called RenderedConst?

Also 🚨documentation police🚨 please add some docs

I'm not aware of any additional data we need at this time. I'd be happy to change it and I'll add some docs too 👍

I know this is essentially self explanatory. Still, a short doc comment would be awesome

@michaelwoerister

Does this code also need to handle statics?

I don't believe so. I was unable to find a failing test case for statics and all of the existing rustdoc tests pass after handling Const and AssociatedConst.

Could the schema::Entry::ast field be removed entirely?

I think I ran into some issues when I tried that but I don't remember clearly. I will investigate that tonight.

schema::Entry::ast is still used by the typeck_tables_of query which calls item_body_tables and the const_is_rvalue_promotable_to_static query which calls a function of the same name.

schema::Entry::ast is still used by the typeck_tables_of query which calls item_body_tables and the const_is_rvalue_promotable_to_static query which calls a function of the same name.

You might be able to remove the metadata-based version of the typeck_tables_of query, since it shouldn't be called by for external items anymore. About const_is_rvalue_promotable_to_static I'm not sure. @eddyb or @oli-obk might know more.

You'd need to move the rvalue_promotable_to_static field up from the Ast to the Entry

Can this be removed too?

Yes, good catch!

You could replace the u8 here and in AssociatedConst with a struct ConstQualif { mir: u8, ast_promotable: bool }.

What does ast_promotable mean?

The rvalue_promotable_to_static: bool field that's currently in Ast.

This changes the behaviour as && binds more tightly — was this intentional?

No, that was not intentional. Good catch!

Also, this would be nicer with a match instead of chained if lets. @wesleywiser, would you mind making a PR with a fix?

Yeah, looks like I messed this up when I pulled the latest changes into my branch. I've opened a quick PR that fixes this (#50114). I'll send a follow up tonight that uses a match for this instead.

When I rebased rust-lang#49991 on `master`, I messed up the merge for this line. I'm reverting this back to the way it was in f15e5c1.

This should ideally call mir_const_qualif itself instead of taking the value as an argument.

I didn't do that because of this call https://github.com/rust-lang/rust/pull/49991/files/4a77d35c1ed89310a0ed128ce931cd4b85ca4cd4#diff-f55f5d2e86bc0e08c341b51fc78b27e4R796

Why would that keep the AST promotability but not the MIR one? I think you just never need either for trait associated consts.
