Struct bevy_save::Rollback

impl Rollback

pub fn from_world(world: &World) -> Self

Returns a Rollback of the current [World] state. This excludes Rollbacks and any saveable that ignores rollbacking.

pub fn from_world_with_filter<F>(world: &World, filter: F) -> Selfwhere F: Fn(&&TypeRegistration) -> bool,

Returns a Rollback of the current [World] state, filtered by filter. This excludes Rollbacks and any saveable that ignores rollbacking.

pub fn apply(&self, world: &mut World) -> Result<(), SaveableError>

Apply the Rollback to the [World].

Errors

See SaveableError

pub fn apply_with_map( &self, world: &mut World, map: &mut EntityMap ) -> Result<(), SaveableError>

Apply the Rollback to the [World], mapping entities to new ids with the [EntityMap].

Errors

See SaveableError

Trait Implementations§

impl CloneReflect for Rollback

fn clone_value(&self) -> Self

Clone the value via Reflection.

Auto Trait Implementations§

impl !UnwindSafe for Rollback

Blanket Implementations§

impl<T> Any for Twhere T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T, U> AsBindGroupShaderType for Twhere U: ShaderType, &'a T: for<'a> Into,

fn as_bind_group_shader_type(&self, _images: &RenderAssets<Image>) -> U

Return the T [ShaderType] for self. When used in [AsBindGroup] derives, it is safe to assume that all images in self exist.

impl<T> Borrow<T> for Twhere T: ?Sized,

const: unstable · source§

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for Twhere T: ?Sized,

const: unstable · source§

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> Downcast<T> for T

fn downcast(&self) -> &T

impl<T> Downcast for Twhere T: Any,

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for Twhere T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send + 'static>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
