Before You Start

Do you have Rust experience? If not, you should learn Rust first.

It’s not a simple framework if you don’t understand the concepts.

It’s too new to code with AI, which means if you are a vibe coder or beginner who depend on AI, you have to understand the concepts first.

To check if you are ready, the concepts you must know are:

rust fundamentals:

• async rust: Future and tokio.
• ownership and life circle: how to use less .clone() and Arc.
• pointers: the difference between &[T], Box<[T]>, Vec<T>, Arc<[T]>.
• memory optimization(optional), especially how to decrease the heap allocation.

architecture:

• RPC: what is RPC and how to use it.
• distributed system: how to solve the data consistency problem and race condition problem.
• event driven: how to design an event driven system.
• inter-process communication: when should you use shared memory and when should you use channel.
• single responsibility principle: what is a single responsibility principle. when you should use it.

functional programming:

• closure: what is a closure. why Processor is like an async closure.
• pipeline: what is a pipeline. how to reuse functions with pipeline.
• map, filter, fold: how to understand these functions.
• partial application: what is partial application. how to use it.
• monads(optional)

You probably don’t know what is NATS. But it’s not a problem. You can learn it easily.
