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>
impl<const SEND: bool> ResourceData<SEND>
sourcepub fn is_present(&self) -> bool
pub fn is_present(&self) -> bool
Returns true if the resource is populated.
sourcepub fn id(&self) -> ArchetypeComponentId
pub fn id(&self) -> ArchetypeComponentId
Gets the ArchetypeComponentId
for the resource.
sourcepub fn get_data(&self) -> Option<Ptr<'_>>
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.
sourcepub fn get_ticks(&self) -> Option<ComponentTicks>
pub fn get_ticks(&self) -> Option<ComponentTicks>
Returns a reference to the resource’s change ticks, if it exists.
