Shell Completions in Rust
If you've ever hit the tab key while typing commands in the shell, you are familiar with the value of shell completions.

Asynchronous Programming in Rust
Asynchronous programming in Rust continues to make exciting strides, including the upcoming stabilization of the futures API . But, while these core APIs make it possible to write async Rust code today, it's not easy: it's a far cry from the smoothness of synchronous code.

The Road to Valhalla
The goal of Project Valhalla is to bring more flexible flattened data types to JVM-based languages, to bring the programming model back in line with the performance characteristics of modern hardware. The core feature is inline classes (known previously as value types ), but such a fundamental perturbation of the JVM…

Developing a Statically Typed Programming Language (2017)
In this blog post we’ll go through a sample implementation of a type checker, interpreter and a transpiler for a basic purely functional programming language, which is based on the lambda calculus. We will do a “full-stack” programming language development by going through formal definition of the language’s syntax…

Why async fn in traits are hard
After reading boat’s excellent post on asynchronous destructors , I thought it might be a good idea to write some about async fn in traits. Support for async fn in traits is probably the single most common feature request that I hear about. It’s also one of the more complex topics. So I thought it’d be nice to do a…
