description:
    This package provides low- and high-level Haskell bindings for [TREXIO, a portable file format for storing wave function data](https://trex-coe.github.io/trexio/).
    Tested with TREXIO versions:

      * 2.5.0
      * 2.6.0

    The vast majority of the bindings in this package is generated via TemplateHaskell from the TREXIO JSON specification, that then defines the C-API.
    For more details see the [TREXIO documentation](https://trex-coe.github.io/trexio/lib.html).
    Consequently, this package is able to adapt to changes in the TREXIO specification, but the Hackage version reflects the canonical upstream TREXIO specification.

    The low-level API is a direct mapping of the C-API, with minimal abstraction, i.e. passing raw pointers around and responsibility for memory management is on the user.
    See the @TREXIO.LowLevel@ module for more details.
    The @TREXIO.LowLevel.Scheme@ module is the Aeson representation of the TREXIO JSON specification and reflects the structure that was used by TemplateHaskell for code generation.
    However, the low-level bindings are very complete and allow for buffered IO of large quantities such as the Electron Repulsion Integrals or Configuration State Functions.

    The high-level API is more haskellish and provides a more type-safe and user-friendly interface to the TREXIO library.
    The @TREXIO@ module provides your entry point to the high-level API.
    Function names are automatically generated by stripping the @trexio_@ prefix from the C-API and converting to camel case.
    Furthermore, @TREXIO.HighLevel.Records@ provides a direct translation of the TREXIO JSON specification to Haskell records (without buffered IO, however).
    The @TREXIO.HighLevel.Records@ is not used for any other purpose within this library, however.

    The high-level API utilises @TREXIO.CooArray@ to provide a more idiomatic interface to sparse arrays used for many high-dimensional quantities within TREXIO.

    These bindings heavily rely on [Massiv](https://hackage.haskell.org/package/massiv) for handling arrays.

    Example usage:

    @
    import TREXIO
    import TREXIO.CooArray
    import Data.Massiv.Array as Massiv

    main :: IO ()
    main = do
        \-- Get the version of TREXIO we have linked against
        ver <- version
        putStrLn $ "TREXIO version: " <> ver

        withTrexio "example.h5" FileWrite Hdf5 $ \\trexio -> do
            \-- Write nuclear coordinates to a TREXIO file
            coords <- Massiv.fromListsM Par
                [ [0. , 0., -0.24962655]
                , [0. , 2.70519714, 1.85136466]
                , [0. , -2.70519714, 1.85136466]
                ]
            writeNucleusCoord trexio coords

            \-- Read reduced 2-electron density matrix (assuming it exists in the example.h5)
            rdm2e <- readRdm2e trexio
            print rdm2e
