So for sending a message from async to sync, you should use the standard library unbounded channel or crossbeam. Similarly, for sending a message from sync to async, you should use an unbounded Tokio mpsc channel.

Webb6 maj 2024 · Channels are also used by the upcoming QUIC implementation currently being developed for .NET 5. If you squint, the System.Threading.Channels library also looks a bit similar to the System.Threading.Tasks.Dataflow library that’s been available with .NET for years. In some ways, the dataflow library is a superset of the channels library; in ... WebbThere are also channels for use outside of asynchronous Rust, such as std::sync::mpsc and crossbeam::channel. These channels wait for messages by blocking the thread, which is not allowed in asynchronous code. In this section, we will use mpsc and oneshot. The other types of message passing channels are explored in later sections.
