pub fn split_source_id(url: &str) -> (Option<&str>, Cow<'_, str>)Expand description
The source an s3://<id>@bucket/key URL names, and the URL without it.
Only S3 URLs carry a source, and only for S3-compatible servers, whose bucket names
repeat from one endpoint to the next. Bucket names cannot contain @, so an @ in
the first segment is always a source. Everything else comes back unchanged.
