Prevent Breaking Code Changes in Future Releases using `non exhaustive` enums in Rust

August 3, 2020August 3, 2020RustEnumerations, Rust, Rust programming language, Rust Projects

Reading Time: 2 minutes Hello everyone, recently I have come across a feature in Rust, known as non_exhaustive. It was introduced in Rust 1.40.0 . This attribute prevents source code-breaking changes in projects downstream. enums can be non-exhaustive or exhaustive, depending upon their needs. A non-exhaustive enum indicates that this enum may get new value in the future. By adding #[non_exhaustive] attribute, we can create a non-exhaustive enum which Continue Reading

Reading Time: 4 minutes As you all know Rust Programming has Futures which helps to make our code Asynchronous. Rust’s Futures are analogous to Promises.This article mainly pertains to the internal working of the Future and we’ll also understand the structure of the Future like how it is defined and how it will execute when it comes into the action. Future: In a Nutshell Future is trait in Rust Continue Reading
