The IntableRaising trait describes a type can be converted to an Int, but the conversion might raise an error.

Any type that conforms to Intable or IntableRaising can construct an Int.

This trait requires the type to implement the __int__() method, which can raise an error. For example:

struct Foo(IntableRaising):
    var i: Int

    fn __int__(self) raises -> Int:
        return self.i

Now you can construct an Int:

foo = Foo(42)
assert_equal(Int(foo), 42)
