Webb4 sep. 2024 · The unbounded function creates a tuple result containing both a sender and a receiver. The sender is used to publish items into the channel, and can be cloned and freely throughout the rust program and across different threads. The receiver on the other hand is a Stream and can be used to process the items sent via the sender asynchronously ... 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.
