Hello there, I am using wit-bindgen 0.3.0, and I wanted to gather all my types like this :

interface types {
  variant error {
    invalid-value(string)
  }

  record plugin-info {
    name: string,
    description: string,
    version: string,
    icon: option<string>,
    url: option<string>
  }

  record plugin-config {
    fs-access: list<fs-access>,
  }

  record fs-access {
    host-path: string,
    fsnotify: bool
  }

  record entry {
    title: string,
    description: string,
    preview: option<string>
  }
}

interface michel-api {
  use self.types.{entry}

  hi: func(name: string) -> string
  send-entry-for-input: func(input: string, entries: list<entry>)
}

interface plugin-api {
  use self.types.{plugin-info, plugin-config, entry, error}

  info: func() -> plugin-info
  config: func() -> plugin-config
  update-config: func(config: plugin-config) -> result<_, error>
  for-input: func(input: string) -> list<entry>
  autocomplete: func(input: string) -> option<string>
  bahouais: func() -> string
}

default world michel {
  import michel-api: self.michel-api

  export plugin-api: self.plugin-api
}

The online editor tells me that my wit file is ok, but the macro doesn't know where to find the objects, I have errors like this :

error[E0422]: cannot find struct, variant or union type `EntryParam` in this scope
 --> src/lib.rs:7:1
  |
7 | wit_bindgen::generate!("plugin" in "../wit");
  | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ not found in this scope
  |
  = note: consider importing this struct:
          crate::types::EntryParam
  = note: this error originates in the macro `wit_bindgen::generate` (in Nightly builds, run with -Z macro-backtrace for more info)

error[E0412]: cannot find type `PluginConfig` in module `super::types`
 --> src/lib.rs:7:1
  |
7 | wit_bindgen::generate!("plugin" in "../wit");
  | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ not found in `super::types`

And more errors like this. What did went wrong?

Oh, well, I changed my wit-bindgen from "0.3.0" to the git repo url, and this is now working..
