RA shows unused attribute warning for all #[inline] annotations

[Robbepop]

I think this is a bug in RA since rustc doesn't have any problems with the same attributes.

According to the screenshot, the warning does come from rustc. Can you give some more context about what code gives the warning?

[Robbepop]

I re-checked and rustc (stable, beta and nightly) really doesn't result in warnings.
However, for the projects I have checked (several) I receive those warnings that you can see.
You can test that for example with one of the smaller projects.
For example this is the line in the screenshot:
https://github.com/Robbepop/string-interner/blob/master/src/lib.rs#L210

@Robbepop I just tested the string-interner repository you mentioned, but I can't reproduce it. (No errors or warnings). Do you enable any feature flags or something special (e.g. cargo clippy? rust version etc..) ?

[edit]
My setup:

Windows 10,
rustc 1.41.0 (5e1a79984 2020-01-27)
rust-analyzer version : rust-analyzer 4741ae7

I also encountered this issue. For me, the issue occurs for https://github.com/rust-osdev/x86_64, but only when I change the "Rust-analyzer > Cargo-watch: Command" from check to clippy.

In my case from what I can see this setting is still check.

@Robbepop does this still happen?

(Marking S-actionable, if you look at this in the future and the OP hasn't answered, ping me so we can close it).

Hard to redo the original checks since the repository I linked to has changed quite significantly.
However, I cannot remember this bug having appeared so I guess we are good to close this issue. ;)
