netcdf3

Description

A pure Rust library for reading and writing NetCDF-3 files.

Technical features

• Read the classic and 64-bit offset NetCDF-3 files :
  • Open the files and parse the headers.
  • Read the variables data from a file.
  • Read the attribute u8 values as UTF-8 string.
  • Read the variable data as N-dimensional arrays (using the crate ndarray).
• Manage the NetCDF-3 structures : dimensions, attributes and variables (create, read, rename, remove).
• Write the classic and 64-bit offset NetCDF-3 files:
  • Binary comparisons are done between the crate outcomes and files produced with the Python library (netCDF4).
  • Also see the Python script pyscripts/create_test_nc3_files.py and the Rust test file tests/tests_write_nc3_files.rs.

Known limitations

• Cannot read and write too large NetCDF-3 files (the slicing arrays is not implemented yet).
• Don't manage yet the special case under which the numrecs value is indeterminate (numrecs = 2^32 - 1) (see the File Format Specifications).
• Don't manage yet the special case under which a vsize value is indeterminate (vsize = 2^32 - 1) (see the File Format Specifications).
