What it does
Use the python!{..} macro to write Python code directly in your Rust code. To reference Rust variables, use 'var , as shown in the example above. var needs to implement pyo3::IntoPyObject . It is possible to create a Context object ahead of time and use it for running the Python code. The context can be re-used for multiple invocations to share global variables across macro calls. As a shortcut, you can assign a python!{} invocation directly to a variable of type Context to create a new context and run the Python code in it. A Context object could also be used to pass information back to Rust, as you can retrieve the global Python variables from the context through Context::get . Since the…from docs.rs

I’m sure many of you are familiar, but there’s a treacherous gap between finding (or building) a model that works in PyTorch, and getting that deployed into your application, especially in consumer-facing applications. I’ve been very interested in solving this problem with a great developer experience. Over time, I gradually realized that the highest-impact thing to have was a way to go from existing Python code to a self-contained native binary—in other words, a Python compiler. I was already pretty familiar with a successful attempt: when Apple introduced armv8 on the iPhone 5s, they…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
