}Expand description
Any data that should last the entire lifetime of the application should be stored in the struct implementing this trait.
Provided Methods§
Sourcefn before_event(&mut self)
fn before_event(&mut self)
Before State::event is called, call this.
Sourcefn draw_default(&self, _: &mut GfxCtx<'_>)
fn draw_default(&self, _: &mut GfxCtx<'_>)
When DrawBaselayer::DefaultDraw is called, run this.
Sourcefn dump_before_abort(&self, _: &Canvas)
fn dump_before_abort(&self, _: &Canvas)
Will be called if State::event or State::draw panics.
Sourcefn before_quit(&self, _: &Canvas)
fn before_quit(&self, _: &Canvas)
Called before a normal exit, like window close
Sourcefn free_memory(&mut self)
fn free_memory(&mut self)
If widgetry determines the video card is low on memory, this may be called. The application should make its best effort to delete any unused Drawables.
