Struct Codec 

pub struct Codec {
    pub name: CodecName,
    pub compressed_size: usize,
    pub level: i32,
    pub shuffle: i32,
    pub compressor: i32,
    pub original_data_type: NDDataType,
}

Codec information attached to a compressed NDArray.

name/level/shuffle/compressor mirror C++ Codec_t and compressed_size mirrors NDArray::compressedSize. original_data_type folds in C++ NDArray::dataType, which “holds the data type of the uncompressed data … used for decompression” (NDPluginCodec.cpp:35-36). The Rust port’s typed NDDataBuffer collapses to raw bytes (U8) once compressed and so can no longer carry the element type; because a Codec exists exactly when an array is compressed, this field is the single source of truth for the original element type on every compressed array (set by the codec plugin on compress, read on decompress).

Fields

name: CodecName

compressed_size: usize

level: i32

shuffle: i32

compressor: i32

original_data_type: NDDataType

Element type of the uncompressed data (C++ NDArray::dataType), retained so decompression can rebuild the correctly-typed buffer.
