compression

type Compression interface {
	// these two should only return once they are completely finished
	// behavior: panic on IO error, panic on compression failure if thought to be infallible, return error on failable compression failure
	Compress(out io.Writer, in io.Reader) error

	Decompress(in io.Reader) io.ReadCloser

	AlgName() string

	// can this compression fail if fed unexpected input?
	// a general purpose compression like zstd or xz should return false, since they work on any arbitrary input bytes
	// special purpose compression such as lepton should return true, since it only works on well-formed jpgs
	Fallible() bool

	DecompressionTrollBashCommandIncludingThePipe() string
