Challenge: Race Condition & Mutex Fix 🏎️🔒 You’re building an async counter where multiple tasks try to update a shared number at the same time. But there’s a problem: Rust doesn’t allow shared mutable access without safety measures. Your Mission: Hints: When you use await, it pauses the task, not the thread. Here’s the distinction: […]
Let me break down the process of creating this chat application into three phases, explaining the shared state aspect and unique challenges compared to typical Arc/Mutex tutorials. Phase 1: Setting Up the Basic Structure In Plain English: First, you’ll need to establish the foundational structure of your application. This means creating the basic server that […]
Writing Data to a File When working with Rust, interacting with external APIs like OpenAI’s ChatGPT or writing data to files is common. In this article, we’ll address a couple of important questions regarding writing a Python script generated from the ChatGPT API to a file and converting data between types in Rust. Specifically, we’ll […]
Rust’s asynchronous capabilities are powerful, allowing developers to execute multiple tasks concurrently with ease. In this article, we’ll explore how to use the futures::future::join_all function along with tokio to manage multiple asynchronous tasks efficiently. Understanding join_all The join_all function, provided by the futures crate, enables us to execute multiple async tasks concurrently and collect their […]
https://github.com/0xPlaygrounds/rig/blob/main/rig-qdrant/examples/qdrant_vector_search.rs In the tuple |(d, embeddings)|, the components correspond to the values yielded by documents.into_iter() Thus: Example of OneOrMany Utility Type in Rust Breakdown: Example Output: In this case, OneOrMany makes it flexible to handle cases where you might have a single embedding or multiple embeddings, while keeping the code concise and readable.
Let’s make something more than the basic WASM example that adds 2 numbers together! https://doc.rust-lang.org/rustc/platform-support/wasm32-wasip1.html We’ll do a toy Bitcoin address validator. (Note, it’s not a real one, we’ll just use SHA256 twice). https://github.com/RGGH/tool_sigcheck 🚀 Rebuild & Run (WASI Preview 1) 1️⃣ Build for wasip1 2️⃣ Run with Wasmer 🔧 Fix: Add _start for WASI […]
Yes, Actix-web can serve a .wasm file, but there are a few nuances when it comes to integrating the logic within the WebAssembly file. While serving static files like images and scripts is straightforward, serving and running a .wasm file containing logic requires a bit more setup. Here’s how you can serve and execute logic […]
Format How do you transform the contents of a HashMap into strings? And more specifically, how do you create multiple strings from a HashMap while using the format! macro? In this article, we’ll explore this in detail with a toy example. The Setup: A HashMap in Rust Let’s begin with a small HashMap containing some […]
Instead of generic parameters in traits, Rust also allows associated types: If you’re new to Rust the first time you see associated types may be with the Iterator trait Example – the associated type is on line 2 Why use associated types? The benefit may become clearer with more functions? Here you can see there […]
From the rig.rs docs: “This module defines a flexible pipeline API for defining a sequence of operations that may or may not use AI components (e.g.: semantic search, LLMs prompting, etc).” The pipeline is a bunch of “ops” or operations that must implement the Op trait. “The Op trait requires the implementation of only one […]
