đŚ Keeping Up With Diesel
Todayâs Issue: Why Rust, Gotchas of Making a Multiplayer Engine in Rust, and Tales of a Curious GreptimeDB Advocator
Hello, Rustaceans
This issue is a little late, thanks to some unavoidable chaos behind the scenes, but hey, better late than never, right? We hope youâll forgive us this time.
In this issue, weâll be highlighting the new features introduced in Diesel v2.3.0, spotlight an amazing Rust project, and share 10 incredible links of the week.
Hereâs issue 86 for you!
MAIN NEWS
đŚ Keeping Up With Diesel
When we first wrote about Diesel back in issue 32, they had just released v2.2 with some new features. Fast forward to last week and v2.3.0 is out, bringing with it some much-requested improvements.
Top of the feature highlight is the shiny new #[derive(HasQuery)], which basically lets you point at a struct and say, âYo, go get me the data.â Itâs a huge quality-of-life bump, no more juggling Selectable and Queryable.
You can now reuse base queries across multiple structs, which is the ORM equivalent of discovering your microwave has an air fryer mode.
But wait, thereâs more: window functions are finally a thing. You can now do fancy SQL analytics like ranking employees by salary or calculating averages per department, all while Diesel holds your hand to make sure your queries arenât accidentally summoning Cthulhu.
And if youâve ever wanted to run Diesel in a browser (because who doesnât dream of debugging databases inside Chrome dev tools?), SQLite now works with WASM out of the box.
Postgres fans also get some love with extended support for ranges, multiranges, arrays, and JSON functions, while SQLite picks up JSON/JSONB tricks of its own. Basically, Diesel 2.3 is trying to make âORM painâ a thing of the past, or at least, the less traumatic kind of pain.
So if youâre tired of writing spaghetti SQL, this release might just be the caffeine shot your queries need.
This release doesnât include any major breaking changes, so you should be mostly fine when upgrading.

PROJECT SPOTLIGHT đĄ
Dora
Dataflow-Oriented Robotic Architecture(DORA) is middleware designed to streamline and simplify the creation of AI-based robotic applications.
It offers low latency, composable, and distributed dataflow capabilities. Applications are modeled as directed graphs, also referred to as pipelines.
Robotics and AI devs need something that can handle distributed dataflows, crunch heavy workloads, and still play nice with Python, Rust, and C++.
Itâs features include:
Plug-and-play nodes - Comes with a buffet of pre-packaged nodes, YOLO, CUDA, PyTorch, Mediapipe, you name it, for faster prototyping.
Arrow-powered communication - Zero-copy data format for lightning-fast message passing without serialization drama.
Cross-language, cross-platform - Python, Rust, C++, Linux, macOS, even Windows, Doraâs got you covered.
If youâre tired of robotics frameworks that feel like duct tape over duct tape, Dora-rs gives you modular, low-latency pipelines that actually deliver.
Dora is open-source on GitHub at https://github.com/dora-rs/dora.
