```python
Subclass of `str` describing a repo URL on the Hub.

`RepoUrl` is returned by `HfApi.create_repo`. It inherits from `str` for backward
compatibility. At initialization, the URL is parsed to populate properties:
- endpoint (`str`)
- namespace (`Optional[str]`)
- repo_name (`str`)
- repo_id (`str`)
- repo_type (`Literal["model", "dataset", "space"]`)
- url (`str`)

Args:
url (`Any`):
String value of the repo url.
endpoint (`str`, *optional*):
Endpoint of the Hub. Defaults to <https://huggingface.co>.

Example:
```py
>>> RepoUrl('https://huggingface.co/gpt2')
RepoUrl('https://huggingface.co/gpt2', endpoint='https://huggingface.co', repo_type='model', repo_id='gpt2')  
>>> RepoUrl('https://hub-ci.huggingface.co/datasets/dummy_user/dummy_dataset', endpoint='https://hub-ci.huggingface.co')
RepoUrl('https://hub-ci.huggingface.co/datasets/dummy_user/dummy_dataset', endpoint='https://hub-ci.huggingface.co', repo_type='dataset', repo_id='dummy_user/dummy_dataset')  
>>> RepoUrl('hf://datasets/my-user/my-dataset')
RepoUrl('hf://datasets/my-user/my-dataset', endpoint='https://huggingface.co', repo_type='dataset', repo_id='user/dataset')  
>>> HfApi.create_repo("dummy_model")
RepoUrl('https://huggingface.co/Wauplin/dummy_model', endpoint='https://huggingface.co', repo_type='model', repo_id='Wauplin/dummy_model')
```

Raises:
[`ValueError`](https://docs.python.org/3/library/exceptions.html#ValueError)
If URL cannot be parsed.
[`ValueError`](https://docs.python.org/3/library/exceptions.html#ValueError)
If `repo_type` is unknown.
