### Describe the bug Rust doesn't make sure to generate the same layout for the same struct defination. Read https://rust-lang.github.io/unsafe-code-guidelines/layout/structs-and-tuples.html for more. ```rust [src/v0_50_to_v0_49.rs:69:9] &new_info = AccessorInfo { scheme: Memory, root: "/", name: "0x7f3a1c00bc60", native_capability: { Stat | Read | Write | Delete | List | Blocking }, full_capability: { Stat | Read | Write | CreateDir | Delete | List | Blocking }, } [src/v0_50_to_v0_49.rs:71:9] &old_info = AccessorInfo { scheme: Memory, root: "/", name: "0x7f3a1c00bc60", native_capability: { Stat | List | Presign }, full_capability: { Stat | Rename | List | Presign }, } ``` ### Steps to Reproduce ```rust use opendal_v0_50 as new_o; #[tokio::test] async fn test_read() { let new_op = new_o::Operator::from_config(new_o::services::MemoryConfig::default()) .unwrap() .finish(); let old_op = opendal_compat::v0_50_to_v0_49(new_op); old_op.write("test", "hello, world!").await.unwrap(); let bs = old_op.read("test").await.unwrap(); assert_eq!(String::from_utf8_lossy(&bs.to_vec()), "hello, world!"); } ``` This test will failed for: ```shell called `Result::unwrap()` on an `Err` value: Unsupported (permanent) at write => service memory doesn't support operation write note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace failures: v0_50_to_v0_49::tests::test_read ``` ### Expected Behavior We expect both read and write can work correctly. ### Additional Context _No response_ ### Are you willing to submit a PR to fix this bug? - [X] Yes, I would like to submit a PR. -- This is an automated message from the Apache Git Service.
