Crate hdf5_metno 

HDF5 for Rust.

This crate provides thread-safe Rust bindings and high-level wrappers for the HDF5 library API. Some of the features include:

• Thread-safety with non-threadsafe libhdf5 builds guaranteed via reentrant mutexes.
• Native representation of most HDF5 types, including variable-length strings and arrays.
• Derive-macro for automatic mapping of user structs and enums to HDF5 types.
• Multi-dimensional array reading/writing interface via ndarray.

Direct low-level bindings are also available and provided in the hdf5-sys crate.

Requires HDF5 library of version 1.8.4 or later. Newer versions will enable additional features of the library. Such items are marked in the documentation with a version number indicating the required version of HDF5. The have-direct and have-parallel features also indicates HDF5 functionality.
