-/// A blocking async executor.
-///
-/// This struct exposes the abstraction of a blocking async executor. It is a global and static
-/// executor which means that it doesn't require for new instances of it to be created, it's a
-/// singleton and can be accessed by any thread that wants to perform some async computation on the
-/// blocking executor thread.
-///
-/// The API of the blocking executor is created in a way so that it's very natural, simple to use,
-/// and unbounded to specific tasks or return types. The following is an example of using this
-/// executor to drive an async computation:
-///
-/// ```rust
-/// use revive_dt_node_interaction::*;
-///
-/// fn blocking_function() {
-///     let result = BlockingExecutor::execute(async move {
-///         tokio::time::sleep(std::time::Duration::from_secs(1)).await;
-///         0xFFu8
-///     })
-///     .expect("Computation failed");
-///
-///     assert_eq!(result, 0xFF);
-/// }
-/// ```
-///
-/// Users get to pass in their async tasks without needing to worry about putting them in a [`Box`],
-/// [`Pin`], needing to perform down-casting, or the internal channel mechanism used by the runtime.
-/// To the user, it just looks like a function that converts some async code into sync code.
-///
-/// This struct also handled panics that occur in the passed futures and converts them into errors
-/// that can be handled by the user. This is done to allow the executor to be robust.
-///
-/// Internally, the executor communicates with the tokio runtime thread through channels which carry
-/// the [`TaskMessage`] and the results of the execution.
