error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.64.0 (a55dd71d5 2022-09-19) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type bin -C embed-bitcode=no -C debuginfo=2 -C incremental

note: some of the compiler flags provided by cargo are hidden

The code snippet is part of an application made with the https://docs.rs/warp/latest/warp/ crate.
I am not allowed to share more of the code, unfortunately.

[compiler-errors]

@AntoineSebert can you verify that this still crashes on nightly Rust?

[AntoineSebert]

This does not crash on nightly Rust, but produces an error E0308:

I had already noticed yesterday that there was an issue in my code and created a workaround.

[compiler-errors]

This should be fixed on stable rust 1.65 (due to #99928), so I'll close it.

[AntoineSebert]

Great, thanks !
