request handler panicked: Can't find [email protected] in AstIdMap

[steffahn]

In this code

struct Foo;

macro_rules! Fooo {
    () => { Foo }
}

trait Trait<T> {
    type Ty: Trait<T>;
}

impl Trait<Fooo!()> for () {
    // <<--- “Implement missing members”
}

fn main() {
    println!("Hello, world!");
}

I’m executing Implement missing members quick fix at the location indicated.

Error message:

probably similar issue to #10388 (we really need a type hir mapping, otherwise this will keep happening wth type macros i reckon)
