Implement default members implements PartialEq::ne incorrectly

[awused]

rust-analyzer version: rust-analyzer 0.0.0 (5342f47 2022-07-09)

rustc version: rustc 1.62.0 (a8314ef7d 2022-06-27)

relevant settings: Neovim with coc-rust-analyzer

I tried implement default members on some code by mistake, but got surprising results. Reproduction:

struct SomeStruct {
    data: Arc<Vec<u8>>,
    field: (u32, u32),
}

impl PartialEq for SomeStruct {
}

It will generate this ne method:

impl PartialEq for SomeStruct {
    fn ne(&self, other: &Self) -> bool {
        self.data == other.data && self.field == other.field
    }
}

The implement missing members works as expected for eq

I think this happens around

rust-analyzer/crates/ide-assists/src/utils/gen_trait_fn_body.rs

Line 396 in 4cbf23c

fn gen_partial_eq(adt: &ast::Adt, func: &ast::Fn) -> Option<()> {

, which doesn't seem to actually look at what method it's implementing.
