+/// Creates an op that passes data asynchronously using raw ui8 buffer.
+///
+/// The provided function `op_fn` has the following parameters:
+/// * `Rc<RefCell<OpState>>`: the op state, can be used to read/write resources in the runtime from an op.
+/// * `argument`: the i32 value that is passed to the Rust function.
+/// * `BufVec`: raw bytes passed along, usually not needed if the JSON value is used.
+///
+/// `op_fn` returns a future, whose output is a JSON value. This value will be asynchronously
+/// returned to JavaScript.
+///
+/// When registering an op like this...
+/// ```ignore
+/// let mut runtime = JsRuntime::new(...);
+/// runtime.register_op("hello", deno_core::json_op_async(Self::hello_op));
+/// ```
+///
+/// ...it can be invoked from JS using the provided name, for example:
+/// ```js
+/// Deno.core.ops();
+/// let future = Deno.core.jsonOpAsync("function_name", args);
+/// ```
+///
+/// The `Deno.core.ops()` statement is needed once before any op calls, for initialization.
+/// A more complete example is available in the examples directory.
