Passerine is a small, extensible functional scripting language with a VM written in Rust, featuring pattern matching, structural types, fibers, and hygienic macros. It is designed to be concise and easily embeddable in Rust applications via an FFI.
Use cases
- embed a scripting language in a Rust application
- write concise scripts with a functional language
- experiment with macro systems and language design
- prototype DSLs with syntactic extension
- learn lambda calculus and language implementation
When to choose
- you need a lightweight embeddable scripting layer in Rust
- you want a minimal functional language with macros and pattern matching
- you are exploring programming language design
When to avoid
- you need a production-ready, stable language
- you require static typing
- you need a large ecosystem, libraries, or long-term support
