Six cohorts have shipped 32 crates each — a few of which now have hundreds of thousands of monthly downloads. Below: spotlights of recent graduates and the things they wrote here.
Every artifact has its source on GitHub, a real README, real docs.rs, and a real "what this is for" story. cargo install works on every one of them.
Marit extended her artifact_01 (kov, the single-thread runtime) into a full work-stealing executor over the four months after the cohort. It now powers the internal jobs system at ferrous-systems.
Dev rewrote his artifact_02 (the lock-free MPSC queue) into a reactive backpressure-aware variant his team uses inside Stripe Connect's payouts pipeline. He shipped it to crates.io two weeks after graduation.
Sasha cleaned up her artifact_03 ESP32-C3 HAL into a production-grade UART driver. It got her three interviews and the firmware-engineer role at Espressif she now holds. The crate is mirrored in the official esp-rs org.
Esme used what we taught in week 10 (proc-macros) to write a derive macro that auto-generates runtime-typed record support for serde-compatible structs — useful in dynamic schemas. Maintained actively post-cohort.
Jules entered cohort_05 having never read the rustc source. Six months later he had landed his 22nd PR — most on the trait-resolver subsystem, two on the borrow checker. Now an r+ on three rust-lang teams.
Takeshi joined cohort_03 already at Fastly. He used artifact_01 + artifact_02 as a starting point for an internal isolate runtime now powering parts of Fastly's edge-compute platform. Shipped to production Q3 '25.
Renée's cohort_02 ship-day repo got polished into the canonical "starter template" now used by every Your Business cohort. Workspace, CI, miri, criterion, MSRV — all wired up. She is now an emeritus mentor.
Noor reframed cohort week_04 (Pin) into a tower-style middleware family for pinned services. Now used inside Bytewax's streaming pipeline. The README alone is a tutorial in projection rules.
