Building an API Client Library with Rust I







The world is intricately connected by billions of electronic devices, with people communicating with friends and family through email and messaging apps. Meanwhile, others are absorbed in a sea of online activities, from web browsing to collaborating on Discord servers and crafting innovative solutions using programming languages like Rust.

In this campaign, we'll embark on an exciting journey to visit the world of APIs (Application Programming Interfaces) and explore effective approaches for learning them. We'll also introduce you to two indispensable tools that will help you learn the basics of APIs and empower you to create your own API library from scratch - all in the powerful language of Rust! 💪

Buckle up and let’s get started!
