Functions

func Decompress

func Decompress(api frontend.API, c []frontend.Variable, cLength frontend.Variable, d, dict []frontend.Variable, level lzss.Level) (dLength frontend.Variable, err error)

Decompress decompresses c into d using dict as the dictionary which must come pre "augmented" it is on the caller to ensure that the dictionary is correct; in particular it must consist of bytes. Decompress does not check this. it is recommended to pack the dictionary using compress.Pack and take a MiMC checksum of it. d will consist of bytes It returns the length of d as a frontend.Variable; if the decompressed stream doesn't fit in d, dLength will be "-1"
