babichjacob-option-and-result 0.2.3

A Python implementation of Rust's Option and Result

🤷 Option and Result

This library uses code copied and pasted from Peijun Ma's option library, which they have generously published under the MIT license. 🙏

This is a Python implementation of Rust's Option and Result types in order to help make fallible functions identifiable and more robust than typical exceptions.

💻 Installation

This package is published to PyPI as babichjacob-option-and-result.

🛠 Usage

from option_and_result import NONE, Some, Ok, Err

maybe_a_number = Some(17)
assert maybe_a_number.unwrap() == 17

nothing = NONE()
assert nothing.is_none()

number_result = maybe_a_number.ok_or("not a number")
assert number_result == Ok(17)

result_that_is_err = Err("gah! an error!")
combinatoric_result = number_result.and_(result_that_is_err)

assert combinatoric_result.unwrap_err() == "gah! an error!"

# more methods on Options and Results are available like the Rust documentation shows

# there is also MatchesNone, MatchesSome, MatchesOk, and MatchesErr
# for use with Python 3.10's new structural pattern matching feature
