Function yrs::ymap_iter_next

#[no_mangle]
pub unsafe extern "C" fn ymap_iter_next(
    iter: *mut MapIter
) -> *mut YMapEntry

Moves current YMap iterator over to a next entry, returning a pointer to it. If an iterator comes to an end of a map, a null pointer will be returned. Yrs maps are unordered and so are their iterators.

Returned values should be eventually released using ymap_entry_destroy function.
