@Xuanwo

OpenDAL has some magic internally, so all services will provide both scan and list support.

I have tried http and redis service, and it seems they don't support list

$ ./target/debug/oli ls ustcmirror://
Error: Unsupported (permanent) at list, context: { service: http } => operation is not supported

Am i missing sth?

service that not support neither list not scan doesn't have this magic.
