Problem description

I play with rustlings. In enum2.rs exercise, line 29(message.call();) plugin show error:
This function takes 1 parameter but 0 parameters were supplied [E0061]
But method call does't have any parameter

impl Message {
    fn call(&self) {
        println!("{:?}", self);
    }
}

Here is example from playground

FYI: when I copy/paste this code from rustlings project to another, then everything work fine.

Hi, thank you for reaching us.
The Rustlings project was developed as an interactive trainer with a command-line interface, so exercise files are not included in the project module tree. You can see a corresponding notification, file is not included in module tree, analysis not available at the top of the code editor window. This means that the Rust plugin cannot analyze the code in this file. You can find detailed information about the modules, packages, and crates at this link
Therefore, as you mentioned, analysis works correctly if you place the exercise code in a new project.
