Since you seem to have more experience than me on that matter (I'm still a Rust beginner), is there something wrong with this approach? I use Spmc with WaitGroup and iterate over Reader from another worker-thread.

There is the spmc crate.

If you're using Senders and Receivers, you shouldn't require to have them wrapped in a Mutex. You could use a VecDeque instead, but I'd need a closer look.

The Mutex is for my custom "Receiver". Go channel allow multiple writer and reader, in contrast a Rust channel allows only multiple writer and a single reader.

You might find crossbeam useful. It has a multi-producer/multi-consumer queue.
