Can I somehow make visible what wit-bindgen generates? If yes, how?

There are multiple ways to invoke wit-bindgen. Are you referring to the Rust macro? If so, the most straightforward way is probably https://github.com/dtolnay/cargo-expand

If you happen to be using vscode with the rust-analyzer extension you can put the cursor on the macro invocation and run the command "rust-analyzer: Expand macro recursively"

Also, if you're using cargo-component, you can find the generated bindings in target/bindings
