The signature and comments for `with_column_renamed` looks reasonable for me
```
/// Rename one column by applying a new projection. This is a no-op if
the column to be
/// renamed does not exist.
pub fn with_column_renamed(
self,
old_name: impl Into<String>,
new_name: &str,
) -> Result<DataFrame>
```
@Omega359 do you think anything still left that can be improved?
