Struct valence::ecs::storage::ResourceData

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§

§

impl<const SEND: bool> ResourceData<SEND>

pub fn is_present(&self) -> bool

Returns true if the resource is populated.

pub fn id(&self) -> ArchetypeComponentId

Gets the ArchetypeComponentId for the resource.

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.

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

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