Struct bevy_ecs::storage::ResourceData

source ·
pub struct ResourceData<const SEND: bool> { /* private fields */ }
Expand description

The type-erased backing storage and metadata for a single resource within a World.

If SEND is false, values of this type will panic if dropped from a different thread.

Implementations§

source§

impl<const SEND: bool> ResourceData<SEND>

source

pub fn is_present(&self) -> bool

Returns true if the resource is populated.

source

pub fn id(&self) -> ArchetypeComponentId

Gets the ArchetypeComponentId for the resource.

source

pub fn get_data(&self) -> Option<Ptr<'_>>

Returns a reference to the resource, if it exists.

§Panics

If SEND is false, this will panic if a value is present and is not accessed from the original thread it was inserted from.

source

pub fn get_ticks(&self) -> Option<ComponentTicks>

Returns a reference to the resource’s change ticks, if it exists.

source§

impl<T> Downcast for T
where T: Any,

source§

fn into_any(self: Box<T>) -> Box<dyn Any>

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.
source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

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

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.
source§

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> From<T> for T

source§

fn from(t: T) -> T

Returns the argument unchanged.

source§

impl<T> Instrument for T

source§

fn instrument(self, span: Span) -> Instrumented<Self>
