Rust Solid WASM Example

Steps I did (as notes):

1. Create this Solid project.
2. Install Rust
3. Install wasm-pack (Use cargo)
4. Create a new Rust project: cargo new --lib hello-wasm
5. In Cargo.toml, add wasm-bindgen as a dependency. (Handles the JS -> Rust communication type generation)
6. Write on the lib.rs (Make a function that I can use. Also call the prelude and macro for wasm_bindgen to setup)
7. Run wasm-pack build --target web on the hello-wasm project. It will create a pkg folder witht he compiled wasm files (Important files: .wasm the module, .js for imports, and .d.ts for types - I think self-explanatory).
