#![cfg_attr(feature = "cargo-clippy", allow(clippy::missing_safety_doc))]

//! Types that can be stored and retrieved from a `HDF5` dataset
//!
//! Crate features:
//! * `h5-alloc`: Use the `hdf5` allocator for varlen types and dynamic values.
//!                     This is necessary on platforms which uses different allocators
//!                     in different libraries (e.g. dynamic libraries on windows),
//!                     or if `hdf5-c` is compiled with the MEMCHECKER option.
//!                     This option is forced on in the case of using a `windows` DLL.
