Rhai logo

Rhai is an embedded scripting language and evaluation engine for Rust that gives a safe and easy way to add scripting to any application.

Supported targets and builds

  • All common CPU targets for Windows, Linux and MacOS.
  • WebAssembly (WASM)
  • no-std
  • Minimum Rust version 1.49

Standard features

Protected against attacks

  • Don't Panic guarantee - Any panic is a bug. Rhai subscribes to the motto that a library should never panic the host system, and is coded with this in mind.
  • Sand-boxed - the scripting engine, if declared immutable, cannot mutate the containing environment unless explicitly permitted.
  • Rugged - protected against malicious attacks (such as stack-overflow, over-sized data, and runaway scripts etc.) that may come from untrusted third-party user-land scripts.
  • Track script evaluation progress and manually terminate a script run.

For those who actually want their own language
