We are excited to announce our August Community Showcase. This event gives individuals of all skill levels a chance to come together and share their experiences with Rust.

Whether you’re working on a personal project, contributing to an open-source initiative, or teaching a concept related to Rust, we invite you to present your work and insights.

Take this opportunity to build your confidence and share what you are doing.

David Haig
Title: Implementing a file system in Rust

exFAT-slim - a deep dive into what goes into implementing an embedded file system in Rust. No allocator, no std library, no previous file system experience, just enough ignorance to start the project and just enough pride to finish it. exFAT is the successor to FAT, and you will see it on large disks and SD cards as the default file system format these days. The last patents for it expired this year, so join me as we take a peek under the hood.

Alexey Ozeritskiy
Title: Making the boundary between SQL and Rust disappear

The talk shows how Rust code can be compiled together with SQL queries using LLVM, removing the usual boundary between SQL and external functions.

Jake Mitchell
Title: Reactive Rust Without the Executor

Building systems that react to data ticking at different frequencies is hard. In an electronic trading system, market data, orders, fills, risk, etc. all arrive at their own rates, and every decision depends on all of them at once. Reactive programming is a powerful abstraction for exactly this: describe what depends on what, and let an engine work out the rest.

Wingfoil draws a hard line between I/O and logic. Wire your calculations as a graph once, and the engine runs it in dependency order, every node once per tick, no locks on the hot path — then uses macros to compile that same wiring into a single monomorphised function. A dense 10×10 graph does a full cycle, all hundred nodes ticking, in 32 nanoseconds—0.32 ns per node —and outperforms Tokio.

Title: Hardening your Rust supply chain security

As the Rust ecosystem grows, projects rely on more and more crates from third-party developers. However, this also increases the chances of importing malicious code. Last week's arrayref incident also brought the topic to the front of mind for the Rust community.

In this talk, we will take an in-depth look at what you can do to make your software supply chain more secure. Luckily, the Rust ecosystem is well-positioned to address these threats, and we have some of the best tools available. In particular, I want to share my experience working with cargo-vet and discuss how to adopt it effectively without hurting developer productivity.
