Derive macros should `#[allow(unused_qualifications)]`

[jsuereth]

I ran into an issue with the following code:

#[derive(Serialize, Deserialize, JsonSchema)]
#[serde(tag = "version")]
#[allow(unused_qualifications)]
pub enum Versioned {
    #[serde(rename = "1")]
    V1(StructureForV1),
    #[serde(rename = "2")]
    V2(StructureForV2),
}

This would result in failures with our lint rules, "unecessary qualification" tagged on the V1 or V2 structures.

To work around this, I just generated the code from the macro, copy-pasted into my file and added #[allow(unused_qualification)].

I'm having difficulty reproducing this - what version of rust are you using?

[jsuereth]

Rust 1.88.0. We also just recently reconfirmed the same issue on Rust 1.89.0.

We're using MSRV - 1.81.0 if that's important too.

I'm still not able to repro this, can you provide a full reproducible example? Or can you share the macro-generated code that violates the lint?
