RustAutoOpaque struct

Sometimes you may want to directly work with the RustAutoOpaque<T> struct. It is currently implemented as (roughly) an Arc<RwLock<T>>. The main API is quite simple:

fn example() {
    let opaque = RustAutoOpaqueNom::new(42);
    *opaque.try_write().unwrap() = 100;
    println!("{}", opaque.try_read().unwrap());
}

There are several variants for reading and writing:

  • try_read, try_write
  • read, write
  • blocking_read, blocking_write

which mimics tokio's RwLock semantics.

There needs to be a lock, because the object can be used by multiple Rust threads concurrently.
