Expand description

Metadata describing compression settings for a dataset.

Fields§

§level: CompressionLevel

Compression level.

§shuffle: bool

Whether shuffle filter is applied before compression.

§chunk_shape: Vec<u64>

Chunk shape used during compression.

§compressed_size: u64

Compressed size in bytes (0 if not yet written).

§uncompressed_size: u64

Uncompressed size in bytes.

Implementations§
