Iterator's Map and Filter

[rvente]

Is there active interest in bringing Map and Filter to rustedpy, possibly under a new repo.

This reminds me of https://github.com/EntilZha/PyFunctional

Many of the implementations are straightforward. It would leverage built-ins as often as possible with the added fluent interface method chaining.

I could take on some of these. I have experience in using mypy to type hint them as well. I would imagine future progress would be contingent on result reaching some critical state, but I thought it was worth asking nonetheless.

May be a good idea to share some hypothetical example code snippets see see how well they would work in Python codebases and explore the possible API design

Sure, that sounds like a good idea. To start off, https://github.com/EntilZha/PyFunctional

Has many code samples that outline the rough style with key differences. I would imagine that rustedpy's implementation would adhere more closely to the naming style of Rust, and use a proper Optional type that can be a specialization of the Result type.

from iter import Iter

integers = range(100)
odds_squared = (
  Iter(integers)
    .filter(is_odd)
    .map(square)
    .collect(list)
)

Initial implementation would likely be in terms of the python builtins map and filter. So this, like PyFunctional is an ergonomic mechanism for processing data.
