Error message is shown, claiming cargo check can give more info; cargo check shows no problems

[parasyte]

I get this error message on a private project when I open any *.rs file. The error only started showing up with a recent rust-ide release. When I run cargo check as instructed, it finishes successfully with no other feedback.

I do not have a Cargo.toml in the root project directory, but this shouldn't really matter, right?

Here's a screenshot of the Atom dev console with the logging from rust-ide. It doesn't really provide any useful information:

You do need a root, or parent, Cargo.toml file otherwise Rls won't work. Only recent versions of Rls have started to actually tell you this, which is why you wouldn't have seen the error before.

You could try adding a very simple one at root:

# Cargo.toml
[workspace]
members = [
    "endeavium-rs",
]

I want to add a better warning here, maybe an additional message to suggest adding a root Cargo.toml. Also probably an ignore for this project button.

Yep, adding a root Cargo.toml does solve this problem for me. Cheers for that.

I'll close this as discussion of how to improve the no root/parent Cargo.toml can happen in #49
