Rust like Option and Result types in Python
Project description
Option
A rust-like Option
type in Python, slotted and fully typed.
An Option
type represents an optional value, every Option
is either Some
and contains Some value, or NONE
Using an Option
type forces you to deal with None
values in your code and increase type safety.
Quick Start
from option import Result, Option, Ok, Err
from requests import get
def call_api(url, params) -> Result[dict, int]:
result = get(url, params)
code = result.status_code
if code == 200:
return Ok(result.json())
return Err(code)
def calculate(url, params) -> Option[int]:
return call_api(url, params).ok().map(len)
dict_len = calculate('https://example.com', {})
Install
Option can be installed from PyPi:
pip install option
