Revert rust-lang#103880 "Use non-ascribed type as field's type in mir" This PR prepares a revert for rust-lang#103880 to fix rust-lang#105809, rust-lang#105881, rust-lang#105886 and others (like the duplicates of the first one), in case an actual fix can't get done today. I've also added the MCVE from rust-lang#105809. There is no MCVE for the rust-lang#105881 and rust-lang#105886 ICEs yet however, so there are no tests for them here, although we'll need one before relanding the original changes. Were this PR to land, it would also reopen rust-lang#96514 as it was fixed by the original PR. Opening as draft to allow time for a possible fix. r? `@jackh726`

This should be fixed in tomorrow's nightly now that #105905 has been merged. However, it would be great to have a minimal example that we could add as a non-regression test. |

I worked on an MCVE. It's maybe not minimal yet, but it's standalone. It only works when building as a library (lib.rs), not from a binary (main.rs) use std::future::{pending, Future};
async fn handle_request() -> Result<(), String> {
loop {}
}
struct Server<S> {
_make_service: S,
}
impl Server<()> {
pub fn bind<S>(_make_service: S) -> Server<S> {
loop {}
}
}
impl<T> Server<T> {
fn with_graceful_shutdown<>(self) -> impl Future<Output = ()>
{
pending()
}
}
pub(crate) async fn create_and_bind(
_: impl Future<Output = ()>,
) -> (impl Future<Output = ()>,) {
let server = Server::bind(handle_request().await);
(async { server.with_graceful_shutdown().await; },)
}
pub async fn new() -> Result<(), String> {
let (_future,) = create_and_bind(async { pending().await }).await;
Ok(())

Thanks a lot. |
