This method is complementary for the feature refcell_leak added in an earlier PR. It allows reverting the effects of leaking a borrow guard by statically proving that such a guard could not longer exist. This was not added to the existing `get_mut` out of concern of impacting the complexity of the otherwise pure pointer cast and because the name `get_mut` poorly communicates the intent of resetting remaining borrows.
Use `ast::MacroDef` instead. Also remove `Session::imported_macro_spans`, external macros have spans now.
It was accidentally merged with the wrong version.
Correctly treat const generic parameters in fresh binding disambiguation
…tolnay Add undo_leak to reset RefCell borrow state This method is complementary for the feature cell_leak added in an earlier PR. It allows *safely* reverting the effects of leaking a borrow guard by statically proving that such a guard could not longer exist. This was not added to the existing `get_mut` out of concern of impacting the complexity of the otherwise pure pointer cast and because the name `get_mut` poorly communicates the intent of resetting remaining borrows. This is a follow-up to rust-lang#68712 and uses the same tracking issue, rust-lang#69099, as these methods deal with the same mechanism and the idea came up [in a review comment](rust-lang#68712 (comment)). @dtolnay who reviewed the prior PR. cc @RalfJung
ast: `Mac`/`Macro` -> `MacCall` It's now obvious that these refer to macro calls rather than to macro definitions. It's also a single name instead of two different names in different places. `rustc_expand` usually calls macro calls in a wide sense (including attributes and derives) "macro invocations", but structures and variants renamed in this PR are only relevant to fn-like macros, so it's simpler and clearer to just call them calls. cc rust-lang#63586 (comment) r? @eddyb
…ckler Implement From<&mut str> for String I ran into this missing impl when trying to do `String::from` on the result returned from this API in the `uuid` crate: https://docs.rs/uuid/0.8.1/uuid/adapter/struct.Hyphenated.html#method.encode_lower I wasn't sure what to put in the stability annotation. I'd appreciate some help with that :)
rustc_metadata: Remove `rmeta::MacroDef` And other related cleanups. Follow-up to rust-lang#66364. r? @Centril
resolve: Fix two issues in fresh binding disambiguation Prevent fresh bindings from shadowing ambiguity items. Fixes rust-lang#46079 Correctly treat const generic parameters in fresh binding disambiguation. Fixes rust-lang#68853
def_collector: Fully visit async functions We forgot to visit attributes previously, it caused ICEs. Special treatment of async functions is also moved from `visit_item` to `visit_fn` to reuse more of the default visitor. Fixes rust-lang#67778.
…-gate, r=oli-obk Return feature gate as a `Symbol` A minor refactoring that will be needed for rust-lang#68940. That PR is blocked on me changing the error comments in a whole lot of UI tests. r? @oli-obk
…e-since, r=Centril Fix "since" field for `Once::is_complete`'s `#[stable]` attribute It was accidentally merged with the wrong version in rust-lang#68945. Thanks @jplatte for noticing. This also needs to be beta backported.
