The async-debug crate makes it easy to debug structs and enums containing values that require an async call to render.

For example: ```rust use tokio::sync::RwLock;

[derive(Debug)]

struct MyStruct { my_value: RwLock }

fn main() {

let mystruct = MyStruct { myvalue: RwLock::from("Hello, world!".tostring()) }; println!("{:?}", mystruct );

}

```

Prints something like: text MyStruct { my_value: RwLock { mr: 536870911, s: Semaphore { permits: 536870911 }, c: UnsafeCell { .. } } }

Along comes Async Debug

Just derive from async_debug::AsyncDebug and add the appropriate attribute!

Add to cargo.toml: toml [dependencies] async-debug = "0.1.0"

```rust use async_debug::AsyncDebug; use tokio::sync::RwLock;

[derive(AsyncDebug)]

struct MyStruct { #[asyncdebug(parse = RwLock::read, clone, ty = String)] myvalue: RwLock }

#[tokio::main]

async fn main() {

let mystruct = MyStruct { myvalue: RwLock::from("Hello, world!".tostring()) }; asserteq!( format!("{:?}", mystruct.asyncdebug().await), "MyStructAsyncDebug { my_value: \"Hello, world!\" }", );

}
