v0.10.0

Fixes

Improved the ergonomics of handling errors from EventProcessor. ProcessOutput has a new method result() to get a WeaselResult.

For example, the following function is now valid:

fn fire_event<R, P>(processor: &mut P) -> WeaselResult<(), R>
where
    R: BattleRules + 'static,
    P: EventProcessor<R>,
{
    DummyEvent::trigger(processor).fire().result()?;
    Ok(())
}
