    dictBuffer: *mut c_void,
    dictBufferCapacity: usize,

ZDICT_trainFromBuffer_cover(): Train a dictionary from an array of samples using the COVER algorithm. Samples must be stored concatenated in a single flat buffer samplesBuffer, supplied with an array of sizes samplesSizes, providing the size of each sample, in order. The resulting dictionary will be saved into dictBuffer. @return: size of dictionary stored into dictBuffer (<= dictBufferCapacity) or an error code, which can be tested with ZDICT_isError(). See ZDICT_trainFromBuffer() for details on failure modes. Note: ZDICT_trainFromBuffer_cover() requires about 9 bytes of memory for each input byte. Tips: In general, a reasonable dictionary has a size of ~ 100 KB. It’s possible to select smaller or larger size, just by specifying dictBufferCapacity. In general, it’s recommended to provide a few thousands samples, though this can vary a lot. It’s recommended that total size of all samples be about ~x100 times the target size of dictionary.
