I'm unable to compile the current trunk due to the following error if using beta
(1.74.0-beta.4 (489647f98 2023-10-21)
) or nightly
(1.75.0-nightly (4b85902b4 2023-11-04)
) Rust.
With both, I get the following error:
error[E0283]: type annotations needed
--> gping/src/main.rs:486:26

486 | .constraints(

= note: multiple `impl`s satisfying `Vec<Constraint>: AsRef<_>` found in the `alloc` crate:
- impl<T, A> AsRef<Vec<T, A>> for Vec<T, A>
where A: Allocator;
- impl<T, A> AsRef<[T]> for Vec<T, A>
where A: Allocator;
help: consider specifying the generic argument

For more information about this error, try `rustc --explain E0283`.
It still compiles fine with stable
(1.73.0 (cc66ad468 2023-10-03)
)
