Typed by default
Use explicit signatures and predictable values when scripts cross process, VM, WASM, or host boundaries.
Rust-inspired scripting for portable runtimes
The script for any Rust projects.
Lightweight, portable, predictable, debuggable.
Design ideas
Small language, explicit runtime boundary.
RustScript keeps scripts readable for Rust users while making host integration clear. Scripts describe control flow and data movement; hosts own privileged operations through registered bindings.
Portable VM core
Compile to compact bytecode that can be embedded in services, UI apps, games, and edge agents.
Host-controlled power
Expose only the functions the host chooses. Scripts remain focused on policy, glue, and application logic.
Cooperative scheduling and yielding
Fuel bounds VM work, Epoch gives hosts wall-clock deadlines, and async host calls can yield or wait at explicit boundaries.
JIT and AOT
Start quickly in the interpreter, trace hot paths through the JIT, or precompile whole programs to skip runtime JIT.
No garbage collector
Rust-style ownership, borrows, and moves keep lifetimes visible to the compiler; shared values release through normal Drop without tracing GC.
Use cases
Where RustScript fits.
Programmable edge
Run routing, filtering, and request policy logic through pd-edge and pd-controller.
Game behavior
Embed scriptable gameplay rules inside Bevy while keeping the core engine in Rust.
Gateway scripting
Define dynamic policies without rebuilding or reloading the proxy.
Embedded scripting
Ship VM bytecode to microcontrollers with micro-rustscript.
Links

micro-rustscript
Run precompiled RustScript VMBC on constrained and embedded targets.
IronRust / WinForms
