研究方向
This issue proposes adding HDF5 reading/writing to Polars. Given the lengthy discussion, a contributor should first read through all comments to understand previous design considerations. The key files to examine are likely in the `polars io` crate, such as `src/serde.rs` or similar. One should consider leveraging an existing Rust HDF5 library like `hdf5` or `hdf5 rs`. The implementation must integrate with Polars' lazy and eager APIs. No linked PR exists, so this is open for fresh exploration.
