Is there a way to use rust-analyzer to iterate over the method signatures of a trait outside the context of an IDE?

More info:
Given a procedural macro that produces some type with a non-pub interior iterator, is it possible to iterate over the signatures of the core::iter::Iterator provided methods so that I can generate convenience methods for my struct with the same names?

1. Ideally, the user should be able to call something like MyCoolStruct::step_by or MyCoolStruct::collect with the same parameters they'd provide were they able to access the inner iterator and use its iterator directly.
2. Unfortunately, I cannot provide access to the inner iterator while maintaining the guarantees I'd like to enforce with this library.

If anyone knows where I could look in the ra documentation, it would be helpful, but I thought I'd ask if anyone has encountered something similar. Thank you.
