Colin D Murphy (Nov 04 2024 at 20:23): Colin D Murphy (Nov 04 2024 at 20:23):Is there a way for a method of a resource to mutate the resource (ie, have a &mut self parameter)?

It looks like the has_own_handle is a thing. Just need to figure out how to use it, but I could be way off.

There are certainly ways around this with Rust, but it would be nice to limit barriers to adoption.

Alex Crichton (Nov 04 2024 at 20:35):Right now Rust bindings require the use of RefCell or other *Cell types for interior mutability. I've long wanted a mode where the cell is automatically used for a particular resource so you don't have to explicitly use it, but I haven't had a chance to fill that out just yet
Colin D Murphy (Nov 04 2024 at 20:37):Yeah. I used a RefCell in my code. Maybe we just need to add an explanation to https://component-model.bytecodealliance.org/design/wit.html#resources
