Dynamically generating and using items using WASM

• tonic

  48 9,013 8.6 Rust

  A native gRPC client & server implementation with async/await support.

  

Hello there. So I need something similar to dynamically loading linked libraries, but not quite. Essentially, I need to call a function which will generate some Rust code (tonic-build to generate Rust bindings from a .proto file if you're interested). Then some code to implement the generated traits needs to be generated (i'm thinking macros is the best way to go for this). The generated structs implementing the tonic generated traits then need to be used normally. All of this needs to happen at runtime. I'm fairly stuck on how to approach this. From reading discussion forums, blogs, etc. WASM seems to be a candidate solution for this kinda problem. Could someone kindly explain how WASM can be of help here? Thanks! :D

• tokio

  196 24,761 9.5 Rust

  A runtime for writing reliable asynchronous applications with Rust. Provides I/O, networking, scheduling, timers, ...

  

But for tonic to work, it would also need to support Webassembly (more specifically: WASI), which would require tokio to support it, which it does not.

Using wasmer you can load WASM binaries and execute them at runtime. I was playing around with this about a year ago and wrote a prototype example: https://github.com/pmsanford/wasmloading

• duct.rs

  4 779 4.6 Rust

  a Rust library for running child processes

This doesn't address the generate-and-build step, but you can probably accomplish that by shelling out (perhaps with duct) to cargo build assuming your runtime environment has the necessary tools installed.
