In RFC : Try-Catch Blocks , someone expressed concern over the discoverability of crates. To improve this situation, I suggested to have a "Crate of the Week" similar to TWIR's "Quote of the Week". To jump-start this, I'm hereby asking you folks for nominations. We seek crates that are useful, unsun…

I'd like to self-nominate meon — a zero-cost declarative flat parsing engine for text formats. It leverages SIMD-accelerated logic for extreme performance and comes with Criterion benchmarks out of the box. Check it out here v0.1.0: GitHub - vgnapuga/meon: Flat, fast and declarative parsing engine…

I’d like to nominate cargo-shed. cargo-shed is a Cargo subcommand and Rust library for static dependency health checks. It helps identify dependency bloat, risky feature selections, duplicate crate versions, potentially unused dependencies, and safe cleanup opportunities in Rust projects. It is in…

Self-nominating cargo-rdme : a cargo command to create your README from your crate’s documentation.

I self-nominate komadori-rayon, which supports multi-reduction for rayon, a famous data-parallelism crate. Multi-reduction means you can do something like max, sum and more in one traversal pass! (But now in rayon’s parallelism) See more in: crates.io docs.rs Github

I self-nominate evocode-tauri, a lightweight desktop app that runs a local HTTP proxy serving as a protocol bridge for Codex — with one core goal: let codex->evocode directly call Anthropic LLM or China LLMs (e.g., Zhipu GLM, Moonshot Kimi, DeepSeek, etc.). Website: evocode — AI Code Assistant, E…

I'd like to self-nominate pcap-toolkit , a CLI for processing, filtering, and replaying PCAP capture files. It started from a colleague's problem: preparing captures for Suricata replay required shifting timestamps to start at the current time. So the tool can edit packets with timestamp shifting, I…

I wish to self-nominate Test That! , a powerful test assertion library for Rust forked from GoogleTest Rust. Test That! lets one easily write test assertions which clearly express the intent of the test and then automatically generates test failure messages which provide the full context on the fail…

I would like to self-nominate deconvolution , a comprehensive image deconvolution and restoration library. Features include known-PSF restoration, blind workflows, PSF/OTF conversion, preprocessing helpers, deterministic simulation fixtures, and support for 2D image arrays and 3D volume deconvolution…

I would like to self-nominate tiny-regex . Small (~2.5KB) regex engine for embedded systems. no_std, no alloc - all storage lives on stack, memoization to prevent catastrophic backtracking.

I'd like to nominate mqtt-typed-client for Crate of the Week. It's a type-safe async MQTT client built on rumqttc. Instead of building topic strings with format!() and parsing them back with split('/'), you declare the topic shape once as a struct with #[mqtt_topic("...")] and get a typed publis…

I'd like to nominate xan for crate of the week. I stumbled upon it on accident, yet was impressed with the TUI-based visualizations and "jq for CSV"-type tooling.
