numpy-ringbuffer 0.2.1

Ring buffer implementation for numpy

Ring (aka circular) buffers backed by a numpy array, supporting:

• Operations from collections.deque

• b.append(val)

• b.appendleft(val)

• b.extend(val)

• b.extendleft(val)

• b.pop(val)

• b.popleft(val)

• The collections.Sequence protocol (unoptimized)

• C-side unwrapping into an array with np.array(b)

• Arbitrary element dtypes, including extra dimensions like RingBuffer(N, dtype=(int, 3))

For example:

import numpy as np
from numpy_ringbuffer import RingBuffer

r = RingBuffer(capacity=4, dtype=np.bool)
r.append(True)
r.appendleft(False)
print(np.array(r))  # array([False, True])
