Rust · rustc · Cargo
Compile typed Rust functions and copied records into a target-specific library. Cargo dependencies join the locked workflow. Deployed artifacts do not need rustc or source files; retained receiver objects and open generics need adapters.

use plugin rust::{rust}
extern rust fn exact(value: int) -> int {
value
}
extern rust fn upper(value: str) -> str {
value.to_uppercase()
}
extern rust async fn later(value: int) -> int {
async { value + 1 }.await
}
extern rust from "./rust_fixtures/math.rs" use {add}
print(exact(9007199254740993)) // expected: 9007199254740993
print(upper("hello Rust")) // expected: HELLO RUST
print(add(left: 20, right: 22)) // expected: 42
print(await later(41)) // expected: 42
Requires the Zolo CLI/host — open in the playground or run locally.
Preparation and deployment
Source-free packaging can retain prepared foreign artifacts, but does not remove runtime or platform dependencies. VM, native and LLVM hosting are covered; foreign bindings reject unsupported WebAssembly targets. The recent provider acceptance covers Windows x64. Python acceptance specifically covers CPython 3.12; other platforms need their own verification.
