zero_buffer is a high-performance, zero-copy, implementation of a byte-buffer for Python.

Documentation is available on ReadTheDocs.

from zero_buffer import Buffer # Create a buffer which has space for 8192 bytes. b = Buffer . allocate ( 8192 ) with open ( path , "rb" ) as f : # Read up to 8192 bytes from the file into the buffer b . read_from ( f . fileno ()) # Create a read-only view of the buffer, this performs no copying. view = b . view () # Split the view on colons, this returns a generator which yields sub-views # of the view. for part in view . split ( b ":" ): print ( part )
