error[E0658]: let...else statements are unstable

#13562

This did not work for me. I still get the same error?

Is there anything else i am missing?

Versions:
rustup 1.25.1 (bb60b1e89 2022-07-12)
rustc 1.66.0 (69f9c33d7 2022-12-12

let-else is stable in 1.66, so if you're getting that error message you can't be compiling with 1.66. Maybe you have a local override, or are running some other cargo binary. Try running rustc --version and cargo --version inside the rust-analyzer folder if you didn't before.

Here are the versions:
rustc 1.66.0 (69f9c33d7 2022-12-12)
cargo 1.66.0 (d65d197ad 2022-11-15)

I dont override version anywhere, im just using some crate from crates.io, but im not sure if that crate can possibly override the version?

[flodiebold]

What do you mean by "I'm just using some crate from crates.io"? The issue you referenced is about compiling rust-analyzer, is that not what you're trying to do?

[nikola-bozin-org]

Ohhh, it seems i created issue in wrong section because i used some crates, and those crates contain the error that i referenced. But yes, compilation did not work.

Do you maybe have any other solutions?

[flodiebold]

If you're just trying to compile some crate and getting this error without rust-analyzer being involved, this is indeed the wrong place for this issue 🙂

If you're just running e.g. cargo check in a project and getting this error, and cargo --version says 1.66, I don't know how that could happen. I would suggest asking the owner of the crate that's failing to build.

Yes, i am running cargo check and my cargo--version is cargo 1.66.0 (d65d197ad 2022-11-15) . Is it possible that crate is overriding version?

[flodiebold]

Your project can have a rust-toolchain file that overrides the version, but that would show up in cargo --version. Dependencies can't override the compiler they're compiled with, everything gets compiled by the compiler you invoked (unless they're doing some build.rs shenanigans).
