Thanks for the ping. It seems to be that here

rust/compiler/rustc_infer/src/infer/error_reporting/need_type_info.rs

Lines 165 to 168 in 993deaa

if let TypeVariableOriginKind::TypeParameterDefinition(name, def_id) = var_origin.kind
&& !var_origin.span.from_expansion()
{
let generics = infcx.tcx.generics_of(infcx.tcx.parent(def_id));

it's not always the parent tcx.parent(def_id) which has generics_of, sometimes its on the def_id as-is. I'm not entirely sure when we need the tcx.parent (IIRC it doesn't work for my test case if I don't add tcx.parent).

Now if I stick to only using def_id and not its parent,

debug!(?def_id);
let generics = infcx.tcx.generics_of(def_id);
debug!("generics: {:?}", generics);
let idx = generics.param_def_id_to_index(infcx.tcx, def_id).unwrap();

the param_def_id_to_index line ICEs on my PR's test case because it can't find the param index for the def_id.

trait T {}

struct S {}

impl S {
    fn owo(&self, _: Option<&impl T>) {}
}

fn main() {
    (S {}).owo(None)
    //~^ ERROR type annotations needed
}

cc @lcnr sorry for the ping, but do you know if impl T here is special somehow? The DefId debug path for my PR's test case seems to have another layer compared to this issue's ICE example, namely {opaque#0}. I think this is why getting param_def_id_to_index for my PR test case's parent worked but not for this ICE?

going to look into this, I think using parent is correct and the bug is somewhere else 😅
