Expand description

Returns compression statistics for a given array and set of algorithms

This is useful for determining which compression algorithm is most effective for a particular dataset.

§Arguments

  • array - The array to test
  • algorithms - List of compression algorithms to test
  • level - Compression level to use for all algorithms

§Returns

A vector of (algorithm, ratio, compressed_size) tuples
