Enum SceneUpdateResult

pub enum SceneUpdateResult<SR: Clone + PartialEq + Debug, SN: Clone + PartialEq + Debug> {
    Nothing,
    Push(bool, SN),
    Pop(Option<SR>),
}

When a scene wants to add or remove a scene from the stack it should return Push or Pop from Scene.update

Variants

Nothing

Do nothing, the current scene remains the foreground scene

Push(bool, SN)

Open a child scene

Arguments

• 0 bool - If true this scene will be closed as well as opening the new scene
• 1 SN - Data for SceneSwitcher so it can create the new scene

Pop(Option<SR>)

Close this scene, data may be included to be returned to the parent scene

Trait Implementations

impl<SR: Clone + Clone + PartialEq + Debug, SN: Clone + Clone + PartialEq + Debug> Clone for SceneUpdateResult<SR, SN>

fn clone(&self) -> SceneUpdateResult<SR, SN>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<SR: Debug + Clone + PartialEq + Debug, SN: Debug + Clone + PartialEq + Debug> Debug for SceneUpdateResult<SR, SN>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<SR: PartialEq + Clone + PartialEq + Debug, SN: PartialEq + Clone + PartialEq + Debug> PartialEq for SceneUpdateResult<SR, SN>

fn eq(&self, other: &SceneUpdateResult<SR, SN>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
