Bringing faster exceptions to Rust
November 6, 2024 RedditThree months ago, I wrote about why you might want to use panics for error handling. Even though it’s a catchy title, panics are hardly suited for this goal, even if you try to hack around with macros and libraries. The real star is the unwinding mechanism, which powers panics. This post is the first in a series exploring what unwinding is, how to speed it up, and how it can

Introducing Hyperlight: Virtual machine-based security for functions at scale - Microsoft Open Source Blog
The Microsoft Azure Core Upstream team is excited to announce the Hyperlight project, an open-source Rust library you can use to execute small, embedded functions using hypervisor-based protection for each function call at scale. And it can do it at a speed that enables each function request to have its own hypervisor for protection. That’s fast. That’s new. In this post, we’ll go deeper into the

The description already lives up to the title. It contains benchmark results telling me that a method on our Rope named point_to_offset is now up to 70% faster. 70%! Throughput increased by 250%. (I can't remember but I'm su

Rust's Sneaky Deadlock With `if let` Blocks
01 Nov, 2024 Rust is my favorite programming language. I've been writing Rust for about 6 years, from college to professionally, and I'm vocal about how helpful the compiler is in catching particularly nasty multithreaded issues and memory bugs. What the compiler doesn't always catch though is deadlocks, which can occur using several well known types like Mutex and RwLock. Generally, this is fine,
