I found a quite helpful way to get a better feeling of async Rust by looking at it from the Go perspective.

Let's compare 4 different command line prompt crates by running their basic examples: cliclack, dialoguer, promptly, inquire.

GitHub: https://github.com/fadeevab/design-patterns-rust 👈 My repository contains 100% fresh unique idiomatic Rust examples covering all 23 classic design patterns.

A few software design patterns are seamlessly integrated into Rust, so we're using them without realizing them. Which is great! A hint: it is 2 creational patterns.

A typical Mediator pattern implementation with other languages is a classic anti-pattern in Rust: many objects hold mutable cross-references on each other, trying to mutate each other, which is a deadly sin in Rust - the compiler won't pass your first naive implementation unless it's oversimplified.
