Add lint for 2229 migrations by arora-aman · Pull Request #80629 · rust-lang/rust

arora-aman · 2021-01-02T20:31:28Z

Implements the first for RFC 2229 where we make the decision to migrate a root variable based on if the type of the variable needs Drop and if the root variable would be moved into the closure when the feature isn't enabled.

By and large, this looks great. I left a few nits.

nikomatsakis · 2021-01-16T10:51:19Z

nit: can we pull the body of this if out into a separate method?

nikomatsakis · 2021-01-16T10:56:03Z

nit: you can use .any() instead =)

nikomatsakis · 2021-01-16T10:57:00Z

Nit: maybe simpler to do root_var_min_capture_list.iter().any(|l| l.place.projections.len() > 0) ?
would we ever capture a and a.b? no, right?

nikomatsakis · 2021-01-16T10:57:55Z

I wonder if we want to consider the Edition too .. e.g., in Edition 2021, maybe this lint should be a no-op

Not important

When I initially wrote this the PR to introduce 2021 edition was in progress, so I didn't think too much at the time. I don't know if we should just ignore lints that are no-op without letting the user know about it.

nikomatsakis · 2021-01-16T11:01:13Z

We don't really need migration here, right? The only drop that will run is still going to run at the same point either way (when the closure is dropped). I agree the analysis as implemented in this PR would be expected to warn, it's just that it's overly conservative.

We don't need migrations here, but this PR doesn't implement the precise path yet. I can add another String to the tuple so that we don't need to move the test when I implement the precise path.

jonas-schievink · 2021-01-30T16:44:02Z

@bors r- based on #80629 (comment)

- This allows us add fake information after handling migrations if needed. - Capture analysis also priortizes what we see earlier, which means fake information should go in last.
