How feasible is to create a WASM plugin system in Rust?

• extism

  46 3,757 9.2 Rust

  The framework for building with WebAssembly (wasm). Easily load wasm modules, move data, call functions, and build extensible apps.

  

take a look at the docs & github if you're interested: https://extism.org & https://github.com/extism/extism

• wasmi

  3 1,327 9.2 Rust

  WebAssembly (Wasm) interpreter.

  

There are lots of solutions to this, I was randomly looking into this yesterday purely out of curiosity and it looks to me like wasmi is the current go-to option.

• fp-bindgen

  24 468 5.0 Rust

  Bindings generator for full-stack WASM plugins

  

fp-bindgen is a library that can help you if you to write custom plugin APIs for such a use case: https://github.com/fiberplane/fp-bindgen

• Ambient

  23 3,724 9.9 Rust

  The multiplayer game engine

  

Yes. I implemented the WASM logic for Ambient. It's all doable, but as the other commenters have mentioned, bindings can be a bit of a pain.

• wasmloading

  2 2 0.0 Rust

I wrote a toy example of this a few years ago. It's probably a little outdated, but it's also probably a little easier to get your head around than reading a full-fledged plugin system in something like lapce: https://github.com/pmsanford/wasmloading

• wasmtime_serde

  2 9 3.4 Rust

  Simple library for serializing complex types to the wasmtime runtime using serde

yes, it's perfectly possible, the biggest hurdle to this is that you need some way to map the data into and out of wasm memory, you can do this manually or use one of the crates that currently solve this problem (I'm author of a github)
