What’s the big deal, why not use Arc and Mutex ? Actors Are Not Rust-Specific – They’re a Universal Pattern!The Actor Model is Language-AgnosticThe Actor Model was actually invented in 1973 by Carl Hewitt – way before Rust existed! It’s a conceptual framework that can be implemented in any language. The WebSocket Challenge Imagine you’re […]
The singleton pattern gives you the benefits of global access while maintaining control over how that global state is created, accessed, and modified. It’s essentially “global variables done right” for cases where you genuinely need global state. To demo this, we’ll code an example to connect to a database. This is just to make the […]
Rather than use Rig.rs or Ollama-rs let’s consider the bare bones of the frameworks that we take for granted.. We make a POST reqwest to the Ollama API and send a body specifying the model and messages ( role & content ). Next – iterate over the stream and display the chunks until there are […]
In Rust, workspaces are a way to organize multiple packages (crates) into a single project with a shared Cargo.lock and output directory (target/). This is especially useful for large projects with multiple components, such as libraries and binaries, that need to share code or build settings. 🧱 What Is a Workspace? A workspace is a […]
AppState provides a clean, type-safe mechanism for sharing crucial resources like database connections, configuration settings, and caches across your application’s request handlers. Without it, developers would need to repeatedly establish database connections or reload configurations for each request, dramatically reducing performance and increasing complexity. By leveraging Actix-web’s AppState pattern, you create more maintainable, efficient, and […]
Introduction Hello and welcome to this tutorial on Schemars in Rust! Today we’re going to explore a powerful tool in Rust’s ecosystem that helps you define, validate, and document your data structures: the Schemars library. If you’ve worked with Rust before, you’re probably familiar with structs and their type system. But what if you need […]
Despite serving different roles, as_ref and Cow share a common goal: enabling flexibility in how data is handled, especially with respect to ownership and borrowing. Both allow your code to work with a broader range of types—as_ref by accepting inputs that can be referenced as a common type, and Cow by returning data that may […]
