Struct GuiLayerPreEvent 

pub struct GuiLayerPreEvent<'a> {
    pub layer: &'a str,
    pub draw: &'a mut dyn DrawContext,
    pub cancelled: bool,
}

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

Fields

layer: &'a str

draw: &'a mut dyn DrawContext

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.
