Project/Tooling Updates
Eurydice is a new tool for automatically adapting small, self-contained Rust codebases for other environments, primarily valuable for keeping evolving projects synchronized.
This GitHub repository documents `v0.2.0` of the `three_dcf_core` Rust crate, now published on `crates.io`, with `three_dcf_index` merged into its core and bundled proto files.
`kinded` v0.5.0 adds `skip_derive`, flexible `attrs` for enums and variants, and a `const fn` `kind()` method for greater control over generated kind enums.
CGP v0.6.1 simplifies provider ergonomics with implicit context types, enhances debugging with `#[check_providers]` for isolated verification, and improves getter trait expressiveness by supporting associated types.
Integrate `hotpath-rs` with LLM agents via MCP to query live Rust application profiling data conversationally.
S2 offers a durable, self-hostable streaming API (s2-lite) with a Rust SDK, leveraging object storage for persistence and supporting in-memory emulation.
Observations/Thoughts
Discover how Rust's unique blend of memory safety, performance, and fearless concurrency makes it a top choice for building robust and blazing-fast network applications.
Introduces Miri, a tool for practical undefined behavior detection in unsafe Rust code, evaluated across 100,000+ Rust libraries.
A podcast offering deep dives into Rust networking, systems programming, and internet protocols, featuring interviews with creators of projects like Tokio, Hyper, Pingora, and rust-url.
A podcast episode discusses new features and changes in the Rust 2024 Edition, including RPIT, let chains, unsafe blocks, and Cargo updates.
Rust Walkthroughs
Details the `cxx` crate's approach to Rust-C++ FFI, specifically exposing Rust/C++ types and defining shared structs.
Rust SIMD benchmarks on Apple M4 show `std::simd` excels with contiguous numerical data but lags behind NEON intrinsics for interleaved data and specific type conversions.

Learn to package your Rust CLI using GitHub Releases, `cargo binstall`, Homebrew, and custom `curl|bash` installers, with insights into security attestations.
Configure `opt-level` for the `dev` profile, distinguishing between your crate and its dependencies.
Research
This paper evaluates the code quality (performance, robustness, maintainability, safety, idiomaticity) of Rust code translated from C by C2Rust, C2SaferRust, and TranslationGym, compared to human-written Rust and analyzed with Clippy and GPT-4o.
