Struct Services 

pub struct Services { /* private fields */ }

Container of engine services — concrete stateful objects with rich APIs (asset loading, serialization, telemetry, DCC orchestration).

Admission criteria. A service is registered here when it is a concrete type with a non-trivial business API (≥ 3 methods that make sense together), lives for the engine lifetime, and is invoked by name. Trait implementations belong in crate::runtime::Backends. Plain shared state belongs in crate::runtime::Resources.

API mirrors the legacy ServiceRegistry (drop-in replacement).

Implementations

impl Services

pub fn new() -> Services

Creates an empty container.

pub fn with_parent(parent: Arc<Services>) -> Services

Creates a container that delegates lookups to parent when a key is absent locally. Local inserts shadow parent entries.

pub fn insert<T>(&mut self, service: T)

where T: Send + Sync + 'static,

Inserts a service, keyed by T’s TypeId. Replaces any prior entry of the same type.

pub fn get<T>(&self) -> Option<&T>

where T: Send + Sync + 'static,

Returns a borrow of the registered service, walking the parent chain on miss.

pub fn require<T>(&self) -> &T

where T: Send + Sync + 'static,

Returns a borrow of the registered service, panicking if absent.

pub fn contains<T>(&self) -> bool

where T: Send + Sync + 'static,

Reports whether a service of the given type is registered.

pub fn len(&self) -> usize

Number of services registered locally (excluding parent chain).

pub fn is_empty(&self) -> bool

Whether no services are registered locally.

Trait Implementations

impl Debug for Services

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

Formats the value using the given formatter.

impl Default for Services

fn default() -> Services

Returns the “default value” for a type.
