 error: could not compile `embassy-executor` (lib) due to 1 previous error

seems to come from this PR #3059

This happens because you're using a too old nightly, try updating it.

[omani]

what does "too old" mean in the context of nightly? a few days?

$ cargo version
cargo 1.83.0-nightly (ad074abe3 2024-10-04)
$ rustc --version
rustc 1.83.0-nightly (9096f4faf 2024-10-05)

[Dirbaio]

ah apologies, it's the other way around. if you're using embassy-executor v0.6.0 from crates.io you're using a too new nightly. Either use an older nightly (before Sep 5th), or use embassy-executor from latest git.

This is the PR that made the breaking change in Rust rust-lang/rust#129919
this is the embassy-executor update #3316

[omani]

thanks.
