Crate async_inspect 

async-inspect 🔍

X-ray vision for async Rust

async-inspect visualizes and inspects async state machines in Rust. See exactly what your futures are doing, where they’re stuck, and why.

Quick Start

use async_inspect::prelude::*;

#[async_inspect::trace]
async fn fetch_user(id: u64) -> User {
    let profile = fetch_profile(id).await;
    let posts = fetch_posts(id).await;
    User { profile, posts }
}

Features
