Compilation error, failed inference on closure about async-scoped

[Verdagon]

Temporary workaround shown in https://github.com/Verdagon/RustFearlessStructuredConcurrency/blob/1734c0a7a2fe779390941a3bfe90e33efc698dfa/src/main.rs

TL;DR: instead of: Scope::scope_and_block(|s| { ... do:

Scope::scope_and_block(|s: &mut async_scoped::Scope<'_, (), async_scoped::spawner::use_async_std::AsyncStd>| { ...

This does require a change to async-scoped source code though, to make spawner public. Specifically, in async-scoped/src/lib.rs, change mod spawner; to pub mod spawner;.

The inference failure is intended as Scope is the general structure that supports both async-std and tokio. To use async-std, make sure you have enabled the use-async-std feature of the crate, and use AsyncScope instead of Scope. Pls. refer example in the docs: https://docs.rs/async-scoped/latest/async_scoped/#scope-api

That solved it! I'm not sure how I missed that, it felt like I'd tried everything at the time.

Thank you for your help!
