A fast, no-copy, buffer for Python

Project description

https://travis-ci.org/alex/zero_buffer.png?branch=master

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)

zero_buffer works on Python 2.6, 2.7, 3.2, 3.3, and PyPy.
