how is lapce-rust compiled

[SingingBush]

I cloned this repo so I can look into writing a new plugin but the project won't build with cargo build as due to missing the crate for core. What steps are being used to build the rust plugin? Will the core of lapce be published to crates.io?

Relates to https://github.com/lapce/lapce/issues/123

It depends on lapce-plugin which is on crates.io. It doesn't depend on lapce core.

It's supposedly to be compiled to WASI so you need to rustup target add wasm32-wasi
