You've chopped off the useful part of the error message. Please provide the entire error message, or as much as you are allowed. |
I'm sorry, here is the full trace with RUST_BACKTRACE=1 |

Minimized to only depend on pin-project-lite: # Cargo.toml
[package]
name = "rustc-bug1"
version = "0.1.0"
edition = "2021"
[lib]
[dependencies]
pin-project-lite = "0.2.11"// lib.rs
use std::future::Future;
use std::pin::Pin;
use std::task::{Context, Poll};
use pin_project_lite::pin_project;
type CancelableResponseFuture = Pin<Box<dyn Future<Output = ()> + Send + Sync>>;
pin_project! {
pub struct Root {
#[pin]
inner: InnerA,
}
}
pin_project! {
pub struct InnerA {
#[pin]
in_flight: InnerB,
}
}
pub struct InnerB {
inner: Pin<Box<dyn Future<Output = ()> + Send>>,
}
impl Root{
fn new() -> Self{todo!()}
}
impl Future for Root {
type Output = ();
fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output> {
todo!();
}
}
pub async fn fetch() {
let fut = async move {
Root::new().await;
};
let b: CancelableResponseFuture = Box::pin(fut);
}Given the words "optimizing mir" in the ICE, probably #130735 (??) |

I'll take a look anyways |

smaller and self-contained: // rustc --crate-type=lib --edition=2021
use std::future::Future;
use std::pin::Pin;
use std::task::{Context, Poll};
struct Root {
inner: InnerB,
}
struct InnerB {

}
impl Root {
fn new() -> Self {
todo!()
}
}
impl Future for Root {
type Output = ();
fn poll(self: Pin<&mut Self>, _: &mut Context) -> Poll<Self::Output> {
todo!();
}
}
async fn fetch() {
let fut = async {
Root::new().await;
};
let _: Pin<Box<dyn Future<Output = ()> + Send>> = Box::pin(fut);

Assigning priority (discussion on Zulip). So, one issue is the ICE, which seems to be on stable since long as per the previous bisection. The other thing I am not sure about is if the code created by the Tauri template should compile or is it correct that exits with an error. @rustbot label -I-prioritize +P-medium |

pretty sure this is a duplicate of #137916 |
