Struct RenderHandEvent 

pub struct RenderHandEvent<'a, 'b> {
    pub render: &'a mut HandRender<'b>,
    pub draw: &'a mut dyn BlockEntityDrawContext,
    pub cancelled: bool,
}

What Hooks::render_hand is told. Each field is that hook’s argument of the same name, described in the hook’s doc.

Fields

render: &'a mut HandRender<'b>

draw: &'a mut dyn BlockEntityDrawContext

cancelled: bool

Whether the event is cancelled: by the game or an earlier listener, or by this one setting it. Only a listener that receives cancelled events (#[listener(receive_cancelled)]) sees true, and setting it back to false lets the game’s behaviour run.
