This is almost certainly to do with something broken in my local target folder (which even zipped is >800mb and I can't sensibly upload that right now), as I've hit this twice now today and both times I've deleted the target folder and the problem goes away. I've hit it with just plain cargo run but I've also been running cargo fmt/clippy/doc on it as well in parallel and although they should all be blocking each other from running, maybe an issue with that setup?

Basically once I hit this cargo run consistently breaks all the time until I wipe target, and then it'll be fine for another few hours of hacking away.

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 1.57.0 (f1edd0429 2021-11-29) running on x86_64-unknown-linux-gnu

note: compiler flags: -C embed-bitcode=no -C debuginfo=2 -C linker=clang -C incremental -C link-arg=-fuse-ld=/usr/local/bin/mold --crate-type lib

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

query stack during panic:
#0 [evaluate_obligation] evaluating trait selection obligation `impl core::future::future::Future: core::marker::Send`
#1 [typeck] type-checking `server`
#2 [type_of] computing type of `server::{opaque#0}`
#3 [check_mod_item_types] checking item types in top-level module
#4 [analysis] running analysis passes on this crate
end of query stack
error: could not compile `cavalcade`
