When I open the following code in VSCode, any action causes Rust Analyzer to panic and restart, and syntax highlighting is severely affected, making it completely unusable.
code snippet to reproduce:
type Alias<T> = T;
trait Trait<T> {
type Assoc;
}
struct Foo;
struct Bar {
x: i32,
}
impl Trait<()> for Foo {
type Assoc = Bar;
}
fn main() {
Alias::<<Foo as Trait<_>>::Assoc> { x: 10 };
}
ra output:
[Error - 11:00:02] Request textDocument/inlayHint failed.
