Re: [PATCH v4 06/11] rust: xarray: add `find_next` and `find_next_mut`

Hi Andreas,

I wonder if we can't hoist most of these calls accessing self.state.state to
the XArrayState directly? For example, I see this in a couple of places:

+            bindings::xas_result(
+                &mut self.state.state,
+                bindings::xa_zero_to_null(bindings::xas_store(
+                    &mut self.state.state,
+                    core::ptr::null_mut(),
+                )),
+            )


How about XArrayState::replace(new: *mut c_void) -> *mut c_void?

Also:

+                state.state.xa_node = bindings::XAS_RESTART as *mut bindings::xa_node;
+                state.state.xa_index = 0;

Could be e.g.: "restart_at(index)”.


WDYT?
