Types

type CompressionType

type CompressionType uint32

CompressionType specifies how a block should be compressed.

const (
	// None mode indicates that a block is not compressed.
	None CompressionType = 0
	// Snappy mode indicates that a block is compressed using Snappy algorithm.
	Snappy CompressionType = 1
	// ZSTD mode indicates that a block is compressed using ZSTD algorithm.
	ZSTD CompressionType = 2
)
