[I] `AsRef` as argument is practically unusable [datafusion]

["m-mueller678 (via GitHub)" <gi...@apache.org>]

m-mueller678 opened a new issue, #18220:
URL: https://github.com/apache/datafusion/issues/18220

   Currently, [datafusion::execution::runtime_env::RuntimeEnv::object_store](https://docs.rs/datafusion/latest/datafusion/execution/runtime_env/struct.RuntimeEnv.html#method.object_store) takes an `impl AsRef<Url>`. Neither `Url` nor `&Url` implement this trait, so I am confused as to how I am supposed to use this. I ended up passing a `Box<Url>`, but I doubt that is the intended way to go. I think it should take a `&Url` instead. If `AsRef<Url>` is actually the intended type, then an example of how to use this would be nice.

   I think what is typically used is `ObjectStoreUrl`
   
   https://docs.rs/datafusion/latest/datafusion/datasource/object_store/struct.ObjectStoreUrl.html#impl-AsRef%3CUrl%3E-for-ObjectStoreUrl
   
   We should improve the documentation about this (aka mention `ObjectStoreUrl` as an option
