Summary

Add boolean operator (and and or) support for several types. I'm pretty new to Rust so any feedback would be great.

A new Type::bool function is created which may also help in #13432 as well.
Contributes to #12701

Test Plan

Cargo tests

Nice, thank you! Not a complete review (I'm on holiday at the moment), just a couple of things I spotted:

Thank you, this is awesome! I think there's one bug, a couple tests that would be good to add, and I think we can also avoid allocating vectors in infer_boolean_expression.

Thanks for these great comments, I'll address them soon.

Something else I was thinking about is to use Type::bool() when inferring the return value of the bool function (ie. understanding x is True in x = bool(1))
It would also be beneficial for testing the bool utility.

What do you think about this? Should we do that? Maybe in another PR?

Yes, that's something we will want. Definitely recommend separate PR for this, as there will be some decisions to make there about how to detect that we are calling the builtin bool type.

nit: I prefer to use ::from methods rather than .into() methods where possible, as it's much clearer when reading things outside of an IDE what exactly you're converting the type into

Red Knot - Infer the return value of bool() (#13538)
ec72e67 
## Summary
Following #13449, this PR adds custom handling for the bool constructor,
so when the input type has statically known truthiness value, it will be
used as the return value of the bool function.
For example, in the following snippet x will now be resolved to
`Literal[True]` instead of `bool`.
```python
x = bool(1)
```

## Test Plan
Some cargo tests were added.
