Moving from TypeScript to Rust in 2023!
Introduction
Are you a TypeScript developer curious about dipping your toes into systems programming? Have you heard of Rust and its focus on safety but thought it needed to be revised or more challenging to give it a try? Well, guess what—you're in for a treat! This blog post will walk you through translating TypeScript code to Rust, highlighting their similarities and critical differences. We'll take a hands-on approach, so you'll come out of this article ready to tackle your next project in Rust.

Basic Syntax and Variables
TypeScript
In TypeScript, declaring a variable is as straightforward as it gets:
Rust
And Rust isn't far off:
?? Takeaway: Rust's type inference is vital, so you often don't need to mention the type explicitly. It's also a little different semantically.
Enums: Enumerating the Differences
TypeScript
TypeScript's way of simulating enums involves some creativity:
Rust
Rust simplifies this by providing first-class support for enums:
?? Takeaway: Rust's native enum type is more robust and less complicated than TypeScript's approach.
Interfaces vs Structs: The Data Model
TypeScript
In TypeScript, you often define object shapes using interfaces:
Rust
In Rust, you use structs for the same purpose:

?? Takeaway: Rust uses structs instead of TypeScript's interfaces to define complex data types.
Functions and Methods: Where the Logic Lives
TypeScript
In TypeScript, most use a function to update user objects:
Rust
In Rust, you're encouraged to define such operations as methods on structs:
?? Takeaway: Rust allows for mutability to be explicitly controlled, making it easier to reason about state changes.
Optional Fields and Error Handling
TypeScript
Rust
?? Takeaway: Optional fields in TypeScript are not too different from Rust; they're just wrapped in an Option type in Rust.
Code Example: Updating User Data
A crucial part of any user management system is updating user records. Let's look at how TypeScript and Rust handle this.

You can check out the TypeScript code for updating a user object here:
Rust
Now let's see how Rust handles the same:
Conclusion: Are You Ready for Rust?
Transitioning from TypeScript to Rust might seem daunting, but as I have demonstrated, these two languages share more similarities than expected. If you're considering taking the plunge, this article has given you the confidence to start. Rust offers different advantages, such as explicit error handling and memory safety, without a garbage collector.
So, are you ready to add another language to your toolbox? Because Rust is worth the learning curve!
