)

type CompressionManager

type CompressionManager struct {
	// contains filtered or unexported fields
}

CompressionManager manages multiple compressors

func NewCompressionManager

func NewCompressionManager() *CompressionManager

NewCompressionManager creates a new compression manager

func (*CompressionManager) Compress

func (cm *CompressionManager) Compress(ctx context.Context, data []byte, compressionType CompressionType) ([]byte, error)

Compress compresses data using the specified compression type

func (*CompressionManager) Decompress

func (cm *CompressionManager) Decompress(ctx context.Context, data []byte, compressionType CompressionType) ([]byte, error)
