This looks like an incremental compilation ICE. Does it disappear after running |
|
I can't reproduce the ICE, so it does look like an incremental bug |

It does. I have cloned that repo, modified the file as in the git diff above and run |

Sorry I had misread.
No, it does not. Sorry for the confusion |

Thanks for the report! I can reproduce with: git clone https://github.com/teloxide/teloxide
cd teloxide/
git checkout fe6429c2790502ae09b04d2659f33e4495f6d314

This is caused by: rust/compiler/rustc_typeck/src/check/fn_ctxt/_impl.rs Lines 1081 to 1082 in b81f581 There is no guarantee that either |

I've never committed to this repository; if you want to guide me to fix this issue, I'm happy to do it. If it's better if you do it, no worries |

Fix panic in 'remove semicolon' when types are not local It's not possible to check if removing a semicolon fixes the type error when checking match arms and one or both of the last arm's and the current arm's return types are imported "opaque" types. In these cases we don't generate a "consider removing semicolon" suggestions. Fixes rust-lang#81839 --- I'm not sure how to add a test for this. I think the test would need at least two crates. Do we have any existing tests that do this so that I can take a look?
