Fluent Rust

As stated in Rustonomicon, Dot operator in Rush does a lot of magics for you. Namely, those are auto-referencing, auto-dereferencing, coercion UNTIL t

Suppose your struct consists of the following field:And you expose public interface to change the state of Transaction:In this case, if the method cha

Using a trait bound with an impl, we can implement methods conditionally for types that implement the specified traits. Here, we implement a method n

If you have written Rust code, you may have heard of so many great things about type state pattern. It’s where the current state of an object is kept

In the last article(https://velog.io/@migorithm/Fluent-Rust-Type-State-Pattern), I covered one way of handling type state pattern in Rust. As saf

Rust의 Type시스템은 강력하다 - 너무 강력해서, 현업코드에서도 타입시스템을 믿고 Refactoring하는 경우가 많다.가령 Enum타입은, 내부 요소로 존재하는 모든 variants들에 대해서, match clause안에서 반드시 매치되길 강제한다. 아래 코드를

In the last post, I talked about Constructor Injection. If you haven't already, make sure to check it out. We want our code to be open to extensibilit

Trait checking implementation is not provided in Rust WITHOUT cost. However, it doesn't mean that you cannot implement it. Here is how.

I was working on implementing my own DI container. I put my business logic and handlers in service layers that are talking against trait(or interface

In general, constuctor injection is good as it enables loosely coupled code. But, things start to look a bit off-putting when their constructors look

Most of your functions that's either "colored" with async or returns impl Future will return the result right away instead of delegating the returning
