scan

method of dascore.io.netcdf.core.NetCDFCFV18

source

scan(
    self ,
    resource: H5Reader ,
    snap: bool = True,
    **kwargs ,
)-> ‘list[ScanPayload]’

Scan NetCDF file metadata without loading the full payload array.

Remote resources are streamed via the h5netcdf engine over the existing h5py handle, so only metadata bytes are fetched and the file is not downloaded.
