What is Benchmarking in Rust? Benchmarking in Rust involves measuring the time taken by specific sections of code to execute. This helps in: Setting Up Benchmarking in Rust By default, benchmarking in Rust is supported using the bencher crate, but it requires using nightly Rust. Here’s how you can set it up: 1. Install Rust … Read more

What is Integration Testing in Rust? Integration testing checks how multiple components of your application work together. Unlike unit tests that focus on individual functions, integration tests focus on testing the interaction between modules, external libraries, or APIs. Rust automatically identifies and runs integration tests located in the tests directory at the root of your … Read more

What is Unit Testing in Rust? Unit testing is the process of testing individual functions or methods in isolation to verify their correctness. In Rust: Why Use Unit Testing? How to Write Unit Tests in Rust Unit tests are written in a dedicated module within the same file as the code being tested. Here’s the … Read more

Why is Testing Important? Testing ensures that your program behaves as expected in different scenarios. Rust’s testing features help: Types of Tests in Rust Rust supports three main types of tests: 1. Writing Unit Tests Unit tests verify that individual functions or methods produce the expected results. Example: Basic Unit Test fn add(a: i32, b: … Read more

What Are Attributes in Rust? Attributes in Rust are metadata added to code elements like structs, functions, or modules. They start with a # symbol and are enclosed in square brackets. For example: #[attribute_name] Attributes tell the compiler or other tools how to treat the code. For instance, you can use attributes to: Types of … Read more

macros are a powerful way to write reusable and flexible code. Macros allow you to generate code at compile time, saving you from writing repetitive patterns. They are especially useful for tasks that require code generation, such as logging, testing or implementing traits for multiple types. What are Macros in Rust? A macro in Rust … Read more

In Rust, futures are a core concept of asynchronous programming. A Future represents a value that might not yet be available but will be produced at some point in the future. Think of it as a promise that something will complete, like fetching data from the internet or reading a file, without blocking the rest … Read more

What is Async Programming? In async programming, tasks can run without waiting for one another to finish. For example, if one task is waiting for data from the network, another task can start immediately instead of being blocked. In Rust: Rust’s async model is highly efficient and well-suited for I/O-bound and event-driven programs like web … Read more

A mutex (short for Mutual Exclusion) is a tool that ensures only one thread can access a piece of data at a time. In Rust, a Mutex is used to safely share data between threads without causing race conditions. This means only one thread can “lock” the data at a time, and other threads must … Read more

In Rust, channels provide a way for threads to communicate safely and effectively. Think of a channel as a messaging system where one thread can send messages, and another thread can receive them. Channels are especially useful for building concurrent applications where threads need to share data or coordinate tasks. What Are Channels in Rust? … Read more
