False Cannot move on primitive types

Environment

• IntelliJ Rust plugin version: 0.2.114.2151-193
• Rust toolchain version: 1.42 nightly
• IDE name and version: CLion 2019.3.3
• Operating system: Windows 10

Problem description

Since the last update, there are a ton of false positive “Cannot move” errors on copying primitive types:

fn get_time_multiplier(&self) -> f32 {
    self.time_multiplier // Cannot move
}

Steps to reproduce

Create a struct with a filed of primitive type and a getter for it.

I have also run into this issue. Code to reproduce: https://pastebin.com/4HS4w9Se The issue is on line 37, self.ft * rhs.ft: self and rhs are red-underlined with the tooltip “Cannot move”.

I am not using the experimental macro expansion. I have tried invalidating my caches and restarting.

I am having this issue. The following is a minimal example:

struct Test {
    value: u32
}

impl Test {
    fn test(&self) -> u32 { self.value } // 'Cannot move'
}

The error only appears when I include the dependency bevy = "0.5" (even though I am not using the package). I have not found any other packages that replicate this behaviour. Earlier versions of Bevy do not cause this behaviour.

I have tried invalidating the cache and restarting, and making a new project. The problem goes away when I set ‘Expand declarative macros’ to ‘Use old engine’.
