rustedpy-maybe 0.0.0

A Rust-like option type for Python

A simple Maybe (Option) type for Python 3 inspired by Rust, fully type annotated.

Installation

Not yet available on PyPI. PyPI package coming soon.

Latest GitHub master branch version:

$ pip install git+https://github.com/rustedpy/maybe

Summary

Experimental. API subject to change.

The idea is that a possible value can be either Some(value) or Nothing(), with a way to differentiate between the two. Some and Nothing are both classes encapsulating a possible value.

Example usage,

from rustedpy-maybe import Nothing, Some

o = Some('yay')
n = Nothing()
assert o.unwrap_or_else(str.upper) == 'yay'
assert n.unwrap_or_else(lambda: 'default') == 'default'
