Trait Updatable 

pub trait Updatable {
    // Required method
    fn update(&mut self, delta_time: f64);
}

A trait for objects that participate in the engine’s update step.

All implementors receive the same fixed-timestep delta time; the engine’s scheduler is responsible for dispatching. Provides a single abstraction over the update methods defined on Entity, Animator, SceneManager, and the World2D / World3D physics containers, enabling generic iteration (e.g. Vec<Box<dyn Updatable>>).

SchedulerState::tick calls into this trait through the TickHandler trait; per-domain implementors (entities, scenes, sprites, physics worlds) expose their own update method that satisfies this contract.

Required Methods

fn update(&mut self, delta_time: f64)

Advance the object’s internal state by the given delta time.

Arguments

• f64 - The delta time in seconds since the last update.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl Updatable for Animator

Forwards Animator::update through the Updatable trait so that collections of heterogeneous updateable objects (entities, animators, physics worlds, scene managers) can be driven by a single scheduler loop.

The inherent Animator::update method is the canonical implementation; this impl exists purely for trait dispatch. The inherent call resolves first when both are in scope, so there is no recursion.

impl Updatable for Entity

Forwards Entity::update through the Updatable trait so that collections of heterogeneous updateable objects can be driven by the scheduler.

The inherent Entity::update method is the canonical implementation; this impl exists purely for trait dispatch. The inherent call resolves first when both are in scope, so there is no recursion.

impl Updatable for PhysicsWorld2D

Forwards PhysicsWorld2D::step through the Updatable trait so that physics worlds participate in the same update loop as entities, animators, and scene managers. The inherent PhysicsWorld2D::step method is the canonical implementation; this impl exists purely for trait dispatch. The inherent call resolves first when both are in scope, so there is no recursion.

impl Updatable for PhysicsWorld3D

Forwards PhysicsWorld3D::step through the Updatable trait so that 3D physics worlds participate in the same update loop as their 2D counterparts, entities, animators, and scene managers. The inherent PhysicsWorld3D::step method is the canonical implementation; this impl exists purely for trait dispatch. The inherent call resolves first when both are in scope, so there is no recursion.

impl Updatable for SceneManager

Forwards SceneManager::update through the Updatable trait so that scene managers can be driven alongside entities, animators, and physics worlds in a single homogeneous update loop.

The inherent SceneManager::update method is the canonical implementation; this impl exists purely for trait dispatch. The inherent call resolves first when both are in scope, so there is no recursion.
