Rollup merge of rust-lang#135118 - ranger-ross:better-docs-on-iter-fns, r=jhpratt Clarified the documentation on `core::iter::from_fn` and `core::iter::successors` This PR clarifies the closure requirements for `core::iter::from_fn` and `core::iter::successors`. `std::iter::successors` in particular is a bit difficult to understand if you are not already familiar with the signature of [`checked_mul`](https://docs.rs/num/latest/num/trait.CheckedMul.html) used in the example. See rust-lang#135087
