Function from_addr 

pub async fn from_addr<BS, DS>(
    uri: &str,
    blob_service: BS,
    directory_service: DS,
) -> Result<Box<dyn BuildService>>
where
    BS: BlobService + Send + Sync + Clone + 'static,
    DS: DirectoryService + Send + Sync + Clone + 'static,

Constructs a new instance of a BuildService from an URI.

The following schemes are supported by the following services:

• dummy:// (DummyBuildService)
• oci:// (OCIBuildService)
• grpc+*:// (GRPCBuildService)
• bwrap:// (BubblewrapBuildService)

As some of these BuildService need to talk to a [BlobService] and [DirectoryService], these also need to be passed in.
