rustacean

A Rustacean is a person who uses, contributes to, or promotes the Rust programming language. The term blends Rust with crustacean, reflecting a lighthearted community culture that identifies members of the Rust ecosystem by a common nickname. It is used to describe developers, contributors, advocates, and enthusiasts who engage with Rust in various ways.

Rustaceans participate in language development, library creation, and ecosystem tooling. They contribute to crates, report issues, write documentation, and help newcomers. Core concepts that many Rustaceans emphasize include Rust’s ownership model, borrowing, lifetimes, and the goal of memory safety without a garbage collector. They also value safe concurrency and high performance, which Rust aims to deliver in systems programming and beyond.

The Rust community has a recognizable identity around its mascot, Ferris the crab, which is often associated with Rustaceans in documentation and events. The Rust project originated at Mozilla Research in the early 2010s and evolved into a foundation-governed ecosystem administered by the Rust Foundation since 2021. Rustaceans participate in a global network of meetups, conferences, and online discussions, and contribute to open-source projects hosted on platforms like Cargo and crates.io. The term is widely used in documentation, blogs, and community discussions to describe both hobbyists and professional developers who work with Rust.
