Axum / tokio shared state channel confusion - help - The Rust ...

November 13, 2021 - I seem to have a conflict between sharing state in Axum, and using a tokio::sync channel rather than a std:sync channel. Tokio says I should be using a tokio::sync channel to communicate between synchronous and asynchronous code ( I understand because it's wrong to block in sync code ). However ...

Wrapping blocking mpsc in async Rust (Tokio) - Stack Overflow

I've posted a separate thread on a rust-lang community and got an answer there.

std::sync::mpsc::channel can be swapped to tokio::sync::mpsc::unbounded_channel, which has a non-async send method. It solves the issue.

rust - Is Axum, with Tokio disabled, still asynchronous? - Stack ...

A function is asynchronous if it is defined as such (async keyword) or returns a Future with the former more or less being syntax sugar for the latter, tokio is merely a runtime to run futures for you (it polls them until they are finished), it's presence is orthogonal to something being asynchronous.

Is State cloned for each request? · tokio-rs/axum · Discussion #1911

Yes the state is cloned for each request. Otherwise you wouldn't be able to extract an owned state.

r/rust on Reddit: Tachyonix: a very fast MPSC async bounded channel

Looks great, thank you for releasing it as a standalone crate! I'm happy to see an in-depth discussion of the trade-offs between various implementations.

Does it use fences or inline assembly for synchronization? I'm asking because they usually cause false positives on Thread Sanitizer, which is my go-to tool for testing concurrency because you can run entire real-world programs with it with reasonable performance (unlike loom or miri).
