列出 julia 中 hdf5 文件的字段

Question

julia 中有没有办法在不加载数据集的情况下列出 hdf5 文件的字段（包括结构、组、维度）？我在 HDF5 包中没有找到类似于 h5ls -r -f 的东西。谢谢。

这是 HDF5 文件结构映射的非常粗略的要点h5_get_struct.jl ，它提供以下输出：

/Users/TM/Temp/test.h5: HDF5.HDF5File (length 10)
 AcquisitionLog: HDF5.HDF5Group (length 0)
 AddTraces: HDF5.HDF5Group (length 5)
    PTR-Instrument: HDF5.HDF5Group (length 0)
    PTR-Misc: HDF5.HDF5Group (length 0)
    PTR-Reaction: HDF5.HDF5Group (length 0)

    TofSupply: HDF5.HDF5Group (length 2)
       TwData: HDF5Dataset () 
       TwInfo: HDF5Dataset (28, 2)

    SumSpectrum: HDF5Dataset (100239, 1)
