this really needs minimization -- there's a lot going on in that test that's probably hiding the underlying cause

matthiaskrgr · 2024-04-16T15:34:55Z

hmm got is as far as

extern crate serde as _serde;

fn visit_map<__A>(self) -> _serde::__private::Result<Self::Value, __A::Error> {

        match __key {
            __Field::__field0 => {
                __field0 = _serde::__private::Some({
                    struct __DeserializeWith<'de, 'a, D> {}
                    impl<'de, 'a, D> _serde::Deserialize<'de> for __DeserializeWith<'de, 'a, D> {
                        fn deserialize<__D>(
                            __deserializer: __D,
                        ) -> _serde::__private::Result<Self, __D::Error>
                        where
                            __D: _serde::Deserializer<'de>,
                        {
                            _serde::__private::Ok(__DeserializeWith {})
                        }
                    }
                });
            }
        }
    
}

Minimized further:

struct Type<T>;

fn visit_map() {
    {
        impl<T> Type<T> {
            fn new() -> Type<T> {
                Type
            }
        }
    };
