Examples

>>> import blosc2
>>> import numpy as np
>>> # Create an SChunk with some data
>>> array = np.arange(10)
>>> ndarray = blosc2.asarray(array)
>>> chunk = ndarray.get_chunk(0)
>>> # Decompress the chunk to convert it into a numpy array
>>> decompressed_chunk = blosc2.decompress(chunk)
>>> np_array_chunk = np.frombuffer(decompressed_chunk, dtype=np.int64)
>>> # Verify the content of the chunk
>>> if isinstance(np_array_chunk, np.ndarray):
>>>         print(np_array_chunk)
>>>         print(np_array_chunk.shape) # Assuming chunk is a list or numpy array
