Making requests to APIs

Our last destination in this chapter brings us away from the server in favor of the other party participating in internet communication: the client. We will use reqwest, which is built around hyper, to create HTTPS requests to web services and parse their data into nicely usable Rust structures. You can also use the content of this recipe to write integration tests for your own web services.

How to do it...

Open the Cargo.toml file that has been generated for you
Under [dependencies], if you didn't do so in the last recipe, add the following lines:

reqwest = "0.8.5"
serde = "1.0.30"
serde_derive = "1.0.30"

If you want, you can go to request's (https://crates.io/crates/reqwest), serde's (https://crates.io/crates/serde), and serde_derive's (https://crates.io/crates/serde_derive) crates.io pages to check for the newest versions and use those ones instead
In the folder src/bin, create a file called making_requests.rs
Add the following code and run it with cargo run --bin making_requests...

Network Programming with Rust

Network Programming with Rust

Rust has steadily become one of the most important new programming languages in recent years. One the one hand, it is low-level enough to provide fine-grained control over memory while providing memory-safety through compile-time validation. Rust also guarantees data race-free parallelism. All these features make it uniquely suitable for writing low-level networking applications. This book will help developers get started on writing such applications in Rust.

Rust High Performance

Rust High Performance

Sometimes it's difficult to get the best performance out of Rust. This book teaches you how to optimize the speed of your Rust code to the level of languages such as C/C++. You'll understand and fix common pitfalls, learn how to improve your productivity by using metaprogramming, and speed up your code by concurrently executing parts of it safely and easily. Master the features of the language that make it stand out and use them to really improve the efficiency of your algorithms.

Hands-On Concurrency with Rust

Hands-On Concurrency with Rust

Writing safe and correct parallel programs is tough. Reasoning about concurrent memory modification is tough; efficiently exploiting the modern computing environment (with its multi-layered caches and deep execution pipelines) is also tough. Most systems programming languages add a further complication: unsafe memory access. The burden on you, the programmer, lies across two domains: understanding the modern machine and understanding your language's pain-points. Rust, with its safe memory model and strong type system, eases this last burden without sacrificing performance. This book will teach you to reason about program performance on modern machines and build fast, memory-safe, and concurrent software in Rust.

Rust Essentials

Rust Essentials

Rust is the new, open source, fast and safe systems programming language for the 21st century, developed at Mozilla Research, and with a steadily growing community. It was created to solve the dilemma between high-level, slow code with minimal control over the system, and low-level, fast code with maximum system control. “Rust Essentials” will give you a head start to solve systems programming and application tasks with Rust. It is no longer necessary to learn C / C++ to develop resource intensive and low-level systems applications.
