Struct Lifetime 

pub struct Lifetime {
    pub remaining: f32,
}

Runtime-only countdown on an entity: seconds remaining before it is automatically removed. A spawn carries it onto short-lived instances (projectiles, debris, timed effects); the graphics step decrements it each frame and despawns the entity (and its descendants) when it reaches zero, reclaiming the GPU draw slots for reuse. World authors never declare this type directly; it is set at spawn time.

Fields

remaining: f32

Seconds left before the entity is despawned.

Trait Implementations

impl Clone for Lifetime

fn clone(&self) -> Lifetime

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Component for Lifetime

const NAME: &'static str = "Lifetime"

The registry name a world authors this component under.

fn from_baked(_bytes: &[u8]) -> Result<Self, CnResult>

Reconstruct this component from a blob record, whose bytes are the serialized runtime component (cook already ran the asset -> component translation). The default rejects: runtime-only components are never stored in a blob, so only loadable types provide an implementation.

fn inject_locator(&mut self, _locator: PayloadLocator)

Called after construction to inject the payload locator from the blob def. Only meaningful for components with a compiled payload. The default implementation does nothing (correct for most components).

fn inject_name(&mut self, _id: AssetId)

Called after construction to inject the asset’s identity from the blob def. Only meaningful for components that look themselves up by id at runtime. The default implementation does nothing.

impl ComponentSlot for Lifetime

const DISCRIMINANT: u8

The component type’s stable id, used as its ComponentId.

fn slot(s: &ComponentStorage) -> &Column<Self>

Borrow this type’s column out of the storage.

fn slot_mut(s: &mut ComponentStorage) -> &mut Column<Self>

Mutably borrow this type’s column out of the storage.

impl Copy for Lifetime

impl Debug for Lifetime

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Lifetime

fn default() -> Lifetime

Returns the “default value” for a type.

impl From<Lifetime> for ComponentAsset

fn from(c: Lifetime) -> Self

Converts to this type from the input type.

impl RuntimeComponent for Lifetime
