REPRODUCER: Change `thread_local_inner` macro transparency to "opaque" #151022

Enselic · 2026-01-12T20:11:11Z

This PR demonstrates that macro transparency "opaque" triggers missing stability attribute errors for other macros in std, not only for Externally Implementable Items (eii) in std. This problem was known before eii. See #146993.

Hey, triage here. Could you clarify what the purpose of the PR is?

Enselic · 2026-01-13T05:45:31Z

Hi and thank you for doing PR triaging!

The purpose of this PR is to demonstrate to the reviewer of #151046 that that PR non-controversial. I will close this PR once that PR has been merged.

(My humble and friendly advice is to not bother doing triaging for draft PRs since they in general are experimental or too early to do review on.)

compiler: Make Externally Implementable Item (eii) macros "semiopaque" Otherwise eiis defined by std will produce large amounts of `missing stability attribute` errors. This problem is not eii specific, as can be seen in rust-lang#146993 and which is demonstrated in rust-lang#151022. As can be seen with ```console $ git grep rustc_macro_transparency compiler/rustc_arena/src/lib.rs:#[rustc_macro_transparency = "semiopaque"] [...] ``` it is very common for macros to use `"semiopaque"`. r? @jdonszelmann Tracking issue: rust-lang#125418 Needed for: rust-lang#150588
