# Runtime Profiles
The Rust package keeps the base crate dependency-light and exposes embedded JavaScript actor execution as an opt-in Cargo feature.
- javascript-quickjs: embedded JavaScript actor code through rquickjs. Enable it with cargo features runtime-quickjs.
- ProcessCodeRuntime remains available for the shared AxCodeRuntime JSONL protocol.
Verify the embedded profile with:
cargo run --example javascript_quickjs --features runtime-quickjs
or from the AxIR toolchain:
tools/axir verify --targets rust --runtime-profiles javascript-quickjs
