Rust community has announced the release of Rust 1.39.0. One of the most notable additions to Rust, with this release, is the arrival of async-await syntax. “Async-await is a way to write functions that can “pause”, return control to the runtime, and then pick up from where they left off. Typically those pauses are to wait for I/O, but there can be any number of uses.”
