• wrapped
  for compressing/decompressing as part of an outer, wrapping format

Macros

• with_core_dtypes
  A macro to help cross the dynamic<->generic boundary for pco core data types.
• with_core_latents

Structs

• Bin
  Part of ChunkLatentVarMeta representing a numerical range.
• ChunkConfig
  All configurations available for a compressor.

  Part of ChunkMeta that describes a latent variable interleaved into the compressed data.
• ChunkMeta
  The metadata of a pco chunk.

  Configures whether integer multiplier detection is enabled.
• Mode
  A variation of how pco serializes and deserializes numbers.
• PagingSpec

Constants

• DEFAULT_COMPRESSION_LEVEL
• DEFAULT_MAX_PAGE_N
• FULL_BATCH_N
  The count of numbers per batch, the smallest unit of decompression.

Functions

• auto_delta_encoding_order
  Automatically makes an educated guess for the best compression delta encoding order, based on nums and compression_level.
