描述

scroll allows deriving decoding and encoding traits, which is just what I want. We should try porting rubble to use that instead of bytes.rs.

We can also try out the zerocopy crate, which allows C-like reinterpretation of arbitrary bytes in safe Rust. Unfortunately it's near impossible to contribute to zerocopy since it's part of fuchsia, but it looks promising.

研究方向
Investigate the current `bytes.rs` file in the rubble repository to understand the existing PDU encoding/decoding. Then, add `scroll` as a dependency and attempt to derive `Pread` and `Pwrite` traits for relevant PDU types. Compare with the existing implementation and ensure existing tests pass. If issues arise, refer to the scroll documentation. Also consider trying the `zerocopy` crate, but note the contributor's comment about limited ability to contribute to it.
