Function zstd_sys::ZSTD_compressStream

pub unsafe extern "C" fn ZSTD_compressStream(
    zcs: *mut ZSTD_CStream, 
    output: *mut ZSTD_outBuffer, 
    input: *mut ZSTD_inBuffer
) -> usize

Alternative for ZSTD_compressStream2(zcs, output, input, ZSTD_e_continue). NOTE: The return value is different. ZSTD_compressStream() returns a hint for the next read size (if non-zero and not an error). ZSTD_compressStream2() returns the minimum nb of bytes left to flush (if non-zero and not an error).
