Trait bevy::asset::AssetLifecycle

pub trait AssetLifecycle: 'static + Downcast + Send + Sync {
    fn create_asset(
        &self,
        id: HandleId,
        asset: Box<dyn AssetDynamic + 'static, Global>,
        version: usize
    );
    fn free_asset(&self, id: HandleId);
}

A trait for sending lifecycle notifications from assets in the asset server.

Required Methods

fn create_asset(
    &self,
    id: HandleId,
    asset: Box<dyn AssetDynamic + 'static, Global>,
    version: usize
)

Notifies the asset server that a new asset was created.

fn free_asset(&self, id: HandleId)

Notifies the asset server that an asset was freed.

Implementations

impl dyn AssetLifecycle + 'static

pub fn is<__T>(&self) -> bool where
    __T: AssetLifecycle, 

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T>(
    self: Box<dyn AssetLifecycle + 'static, Global>
) -> Result<Box<__T, Global>, Box<dyn AssetLifecycle + 'static, Global>> where
    __T: AssetLifecycle, 

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T>(
    self: Rc<dyn AssetLifecycle + 'static>
) -> Result<Rc<__T>, Rc<dyn AssetLifecycle + 'static>> where
    __T: AssetLifecycle, 

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T>(&self) -> Option<&__T> where
    __T: AssetLifecycle, 

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T> where
    __T: AssetLifecycle, 

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.
