I agree. For example, most of Rust libraries uses the drop handler (something like desctructors) to close a file descriptor. However it has problems since in async model closing is also async and it may return an error. So in tokio-uring explicit async close will be provided. https://github.com/tokio-rs/tokio-uring/pull/1/files#diff-3d...

And you can call close like: file.close().await.unwrap(); https://github.com/tokio-rs/tokio-uring/pull/17/files#diff-b...

Note that there are ideas to fix this issue in the async foundations WG. It's arguably more of a problem with async as implemented in Rust than with the concept of RAII.
