Rust Poland Meetup x Poznan

History in the making! This isn’t just another meetup—it’s the very first official Rust Poland Meetup, and we’re throwing open the doors to all Rustaceans across the country.

Join us on July 2nd, 2025 for a landmark evening of code, community, and chaos (the good kind). We’re bringing together the best of Rust Gdańsk’s energy and scaling it nationwide—with talks, demos, networking, and a few surprises you won’t see coming.

Oh, and meet Compiled—the Rust powerhouse behind Rust Poland. Think of us as the build system for this community: optimizing connections, caching knowledge, and linking awesome people. More on that soon…

Talk #1: Ratatui - Are We Embedded Yet?
Speaker: Jagoda Ślązak
Ratatui revolutionized terminal UIs in Rust—but what if we broke it out of the terminal? Jagoda explores how Ratatui is escaping its console confines and thriving in the wildest corners of embedded systems.
This talk dives into Mousefood, an embedded-graphics backend bringing Ratatui to tiny screens, plus the quest for no_std compatibility. You’ll also meet Ratatui’s eclectic siblings: Ratzilla (for the web), ratatui-uefi, and soft_ratatui. Ever wanted to build your own backend? Jagoda will show you how—and demo dev boards running Ratatui in places you’d least expect.
Stick around to tinker with live hardware and chat about the future of TUIs everywhere.

Talk #2: Parsing 600KB JSON on a 264KB Raspberry Pi Pico W
Speaker: Marcin Szymczak
Let’s embark on a journey to build an IoT device that shows real-time Gdańsk ZTM bus departures—powered by a Raspberry Pi Pico W and Rust, all the way down.
But there’s a twist: with only 264 KB of RAM, the Pico W can’t handle the massive 600+ KB JSON responses from the API in one go. That means traditional parsers like nom, winnow, and chumsky just won’t cut it.
This talk, the first in a series, covers the design and development of a custom parser combinator library built to process streaming JSON on constrained hardware. It's a tale of limitations, creativity, and bare-metal Rust hacking.
