I assume this is due to changes in the latest Rust version. Also happens to me using rustc 1.28.0and rustc 1.30.0-nightly

error[E0207]: the type parameter `O` is not constrained by the impl trait, self type, or predicates

There is this error in the log too:

error[E0432]: unresolved import `alloc::arc`
  --> src/prelude/no_std.rs:17:16
   |
17 | pub use alloc::arc::{Arc, Weak};
   |                ^^^ Could not find `arc` in `alloc`
