Decode decodes src into dst, returning both the number of bytes written to dst and the number consumed from src.

Encode encodes src into at most MaxEncodedLen(len(src)) bytes of dst, returning the actual number of bytes written.

MaxEncodedLen returns the maximum length of an encoding of n source bytes.

NewDecoder constructs a new ascii85 stream decoder.

NewEncoder returns a new ascii85 stream encoder.
