  "message": "Rollup merge of #157166 - cjgillot:retype-context-after, r\u003doli-obk\n\nChange type of async context parameter after state transform.\n\n`Future::poll` expects a `\u0026mut std::task::Context\u003c\u0027_\u003e`. Meanwhile, async coroutines use `std::future::ResumeTy` as resume parameter. This is meant to workaround the limitations of borrowck, which cannot prove that coroutines implement `for\u003c\u0027a, \u0027b\u003e CoroutineTrait\u003c\u0026\u0027a mut Context\u003c\u0027b\u003e\u003e`.\n\nIn the coroutine state transform, we need to change the signature from `ResumeTy` to the proper `\u0026mut Context\u003c\u0027_\u003e`. The current code attempts to find locals that have type `ResumeTy` to change their type. This is needlessly complex and relies on undocumented behaviour of the MIR builder.\n\nInstead, this PR proposes to replace the `ResumeTy` argument with a new local, with value `ResumeTy(transmute(context))`.\n\nBased on https://github.com/rust-lang/rust/pull/156875.\n",
