Rust error on pre_upgrade and post_upgrade attributes

[roman-kashitsyn]

Hi @rem.codes!

@rem.codes

everything works like it should

Could you please clarify what you mean by that? Does the canister build when you run cargo?

My guess that it might be purely an IDE problem. I wonder if replacing #[pre_upgrade] with #[export_name = "canister_pre_upgrade"] and #[post_upgrade] with #[export_name = "canister_post_upgrade"] could help your IDE figure out what’s going on.
