Crate netcdf_reader 

Pure-Rust NetCDF file reader.

Supports:

• CDF-1 (classic): CDF\x01 magic
• CDF-2 (64-bit offset): CDF\x02 magic
• CDF-5 (64-bit data): CDF\x05 magic
• NetCDF-4 (HDF5-backed): \x89HDF\r\n\x1a\n magic (requires netcdf4 feature)

Example

use netcdf_reader::NcFile;

let file = NcFile::open("example.nc").unwrap();
println!("format: {:?}", file.format());
for var in file.variables().unwrap() {
    println!("  variable: {} shape={:?}", var.name(), var.shape());
}

Modules

classic

Classic (CDF-1/2/5) NetCDF file format support.

error

masked

_FillValue / missing_value masking for NetCDF variables.

nc4

NetCDF-4 (HDF5-backed) format support.

types

unpack

scale_factor / add_offset unpacking for NetCDF variables.

user_defined

Decoders for NetCDF-4 user-defined data values.

Structs

BlockCacheStats

Point-in-time statistics for BlockCacheStorage.

BlockCacheStorage

Block-aligned LRU cache for any random-access storage backend.

BytesStorage

In-memory storage backed by owned bytes.

ChunkCacheStats

Point-in-time statistics for a ChunkCache.

DatasetChunk

One decoded chunk from a chunked dataset.

DatasetChunkIterator

Iterator over decoded chunks in a chunked dataset.

FileStorage

File-backed storage that serves explicit byte ranges via positional reads.

FilesystemExternalFileResolver

Filesystem resolver for external raw data files.

FilesystemExternalLinkResolver

Filesystem resolver for external links. Linked files are cached after the first successful open.

MmapStorage

In-memory storage backed by a read-only memory map.

NcFile

An opened NetCDF file.

NcOpenOptions

Configuration options for opening a NetCDF file.

NcSliceIterator

Lazy iterator over slices of a variable along a given dimension.

RangeRequestStorage

Storage backed by a caller-provided byte-range reader.

StorageBuffer

An immutable byte range returned by a storage backend.

Enums

NcFormat

NetCDF file format.

NcMetadataMode

NetCDF-4 metadata reconstruction policy.

Traits

ExternalFileResolver

Resolves file names from HDF5 External Data Files messages to storage.

ExternalLinkResolver

Resolves HDF5 external links to another opened file.

NcReadable

Trait alias for types readable from both classic and NetCDF-4 files.

Storage

Random-access, immutable byte storage for HDF5 parsing and reads.
