Lazy generator pipelines

sloths

Lazy iterator pipelines for Python.

sloths is a library providing a chainable interface to easily compose lazy iterator pipelines in Python. The interface is largely inspired by Rust's Iterator trait (although it's not a carbon copy).

The 2 primary goals of the library are:

• Provide an easy to use, chainable and typed API for composing generator pipelines.
• Make it easy to control peak memory usage and throuhgput on large source datasets or long running input streams.

>>> from sloths import Stream
>>> Stream(range(100_000)).enumerate().filter(lambda x: x[1] % 3 == 0).skip(3).take(5).collect()
[(9, 9), (12, 12), (15, 15), (18, 18), (21, 21)]

For more examples see doctests within the code or usage.md.
