Crystal vs Rust: What are the differences?
Crystal: Fast as C, slick as Ruby. Crystal is a programming language that resembles Ruby but compiles to native code and tries to be much more efficient, at the cost of disallowing certain dynamic aspects of Ruby; Rust: A safe, concurrent, practical language. Rust is a systems programming language that combines strong compile-time correctness guarantees with fast performance. It improves upon the ideas of other systems languages like C++ by providing guaranteed memory safety (no crashes, no data races) and complete control over the lifecycle of memory.
Crystal and Rust can be primarily classified as "Languages" tools.
"Compiles to efficient native code" is the top reason why over 27 developers like Crystal, while over 81 developers mention "Guaranteed memory safety" as the leading cause for choosing Rust.
Crystal and Rust are both open source tools. It seems that Rust with 36.9K GitHub stars and 5.81K forks on GitHub has more adoption than Crystal with 13.4K GitHub stars and 1.05K GitHub forks.
According to the StackShare community, Rust has a broader approval, being mentioned in 38 company stacks & 102 developers stacks; compared to Crystal, which is listed in 7 company stacks and 14 developer stacks.
