Rust Example Modules

This directory contains example WASM modules implemented with Rust. These examples were used to experiment how we can pass data between runtime and module.

Build

We can't use a Cargo workspace here because we want to build the individual crates for different targets. Some for wasm32-unknown-unknown and some for wasm32-wasi.

Run ./build.sh to build all modules with the correct target.

./build.sh

The target directory for all modules is set to ./target (see .cargo/config), so you'll find the compiled wasm modules in this directory under ./target/.

Modules

The -raw modules use the method to pass data between host and module described in a blog post of Radu Matei. The -wasi modules are compiled with the target wasm32-wasi and use the standard input and standard output to pass data between host and module. The k8s- modules show how to process a Kubernetes TokenReview object. For this we use the k8s-openapi and serde_json crates.
