call-seq: flush(flush = Zstdlib::SYNC_FLUSH) -> String flush(flush = Zstdlib::SYNC_FLUSH) { |chunk| ... } -> nil
This method is equivalent to deflate('', flush). This method is just provided to improve the readability of your Ruby program. If a block is given chunks of deflate output are yielded to the block until the buffer is flushed.
See Zstdlib::Deflate#deflate for detail on the +flush+ constants NO_FLUSH, SYNC_FLUSH, FULL_FLUSH and FINISH.
