Rust & Qdrant
November 28, 2024 / Last updated : December 4, 2024 admin AI ML

Qdrant & Rust – embeddings

While most examples for performing embeddings will be Python code, Rust is better when performance, safety, and scalability are critical. Most examples/tutorials stick to Python, maybe it’s easier to start with but let’s look beyond “getting started”. Let’s explore Qdrant some more, this time we’ll delve into the Rust client plus fastembed. (Note: If you […]

tokio::spawn

Tokio is an asynchronous runtime for Rust. “It provides the building blocks needed for writing network applications.” – It’s pretty much the de-facto standard for Rust! Before we look at “spawn” let’s review what tokio is, how to use it, and look at what tasks are. tokio::main The #[tokio::main] function is a macro. It transforms […]

Many threads and primarily read-heavy operations? RwLock minimizes contention by allowing multiple threads to read in parallel.
November 25, 2024 / Last updated : November 26, 2024 admin Rust Programming

When or why should I use a Mutex over an RwLock?

TL;DR – use the “R” in RwLock as “R” for READ – i.e when there are lots of reads/Read mostly, use RwLock Choosing between a Mutex and an RwLock in Rust depends on the nature of the access patterns and the trade-offs you’re willing to make in your program’s concurrency model. Here’s a detailed breakdown […]

Displaying Secret Data in Binary Format (Rust Code)

In this article, we will explore how to format and display byte data in Rust. Specifically, we’ll focus on a simple program that formats a secret (a Vec<u8>, or vector of bytes) as a binary string. Understanding the Code Here is the Rust code that we will break down: 1. Defining the Struct In this […]

Bitwise operations – Combining 1D Arrays into 4-Byte Variables in Rust

Bitwise operations When working with data processing in Rust, there are times you may need to efficiently combine elements from an array into a single variable. This tutorial explains how to take four elements from a 1D array of bytes (u8) at a time and pack them into a single 4-byte variable (u32). This approach […]

lazy static (Rust)

Here’s an example demonstrating how to use lazy_static to initialize a global logger with thread-safe access in Rust. The code is structured to illustrate safe concurrency and the advantages of lazy initialization while remaining simple enough for a beginner to grasp. lazy_static: Mutex for Thread Safety: Global Logger: Future Expansion:

Rust Benchmark

using the criterion crate This is a very very basic demo I made to learn how to benchmark my own function. I made a new project, added a lib.rs and then made a function inside lib.rs called “cycler” This is a tiny function so won’t really make full use of the benchmarks but I wanted […]

Understanding 1D Arrays for 2D Pixel Storage in Graphics

Let’s look at how each pixel’s colour is stored in a single 32-bit integer using the RGBA format 1D Array Representation The buffer is a 1D array that stores the pixel colors for each pixel in the window. The array’s length is width * height, and each entry in the array is a 32-bit integer […]

flatten v flat_map

flatten v flat_map – what’s the difference? In Rust, flat_map and flatten are both methods used for transforming and simplifying nested structures, but they serve slightly different purposes and apply to different contexts. 1. flat_map Example: Explanation: 2. flatten Example: Explanation: Key Differences flatten v flat_map – Summary Table Method When to Use Produces Example […]

Arithmetic Sequence in Rust

https://www.codewars.com/kata/52de553ebb55d1fca3000371/train/rust Try the challenge on CodeWars first – and then have a look at my solution which is mainly based on this challenge. What did I learn from this? Well, I worked out that using a HashMap was a neat way to identify the gap that was different to the others. What else? Starting from […]
