Documentation build failed for `teloxide` v0.10.1

[hirrolot]

The full log is available from this link: https://docs.rs/crate/teloxide/0.10.1/builds/597656.

Meta

From the aforementioned link:

# rustc version
rustc 1.64.0-nightly (62b272d25 2022-07-21)
# docs.rs version
docsrs 0.6.0 (19b354a 2022-07-16)

[compiler-errors]

Do you have a more concise way of reproducing this? I can't seem to get it to ICE when I run with +nightly-2022-07-21, no matter if I use cargo +nightly-2022-07-21 rustdoc, etc.

[compiler-errors]

nvm, should be using +nightly-2022-07-22..

[WaffleLapkin]

This is actually reproducible even with teloxide-core. It seems to only ICE with nightly feature.

Command for reproduction: cargo +nightly-2022-07-22 c --features=nightly

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

We don't use nightly feature much, so it should be easy, to make a MRE, I'll try.

[compiler-errors]

I found an MRE. I'll put up a fix in a second.

[WaffleLapkin]

I found a MRE too :(

#![feature(type_alias_impl_trait)]

#[pin_project::pin_project]
pub struct Send {
    #[pin]

mod tait {
    pub(crate) type Send = impl ::core::future::Future<Output = ()>;

    pub(crate) fn _def() -> Send {
        async {}
    }
}

[compiler-errors]

+1, I basically reproduced that in the UI test https://github.com/rust-lang/rust/pull/99666/files#diff-269b1c1ea2d431a283067ef6982b52c20379f0631bc6d3714cc2cfb1429907e0 but manually expanding the part of the pin_project macro that causes the ICE.
