func main() {
	Flate()
	Zlib()
	Gzip()
}

//Flate Example
func Flate() {
	compressor := &compress.Compressor{Type: compress.Flate, Level: compress.DefaultCompression}
	compressBytes := compressor.Compress(readyBytes)
	uncompressBytes := compressor.Uncompress(compressBytes)
	fmt.Printf("flat %d->%d->%d\n", len(readyBytes), len(compressBytes), len(uncompressBytes))
}

//Zlib Example
func Zlib() {
	compressor := &compress.Compressor{Type: compress.Zlib, Level: compress.DefaultCompression}
	compressBytes := compressor.Compress(readyBytes)
	uncompressBytes := compressor.Uncompress(compressBytes)
	fmt.Printf("zlib %d->%d->%d\n", len(readyBytes), len(compressBytes), len(uncompressBytes))
}

//Gzip Example
func Gzip() {
	compressor := &compress.Compressor{Type: compress.Gzip, Level: compress.DefaultCompression}
	compressBytes := compressor.Compress(readyBytes)
	uncompressBytes := compressor.Uncompress(compressBytes)
	fmt.Printf("gzip %d->%d->%d\n", len(readyBytes), len(compressBytes), len(uncompressBytes))
}

Output

flat 512->410->512
zlib 512->412->512
gzip 512->420->512
