Struct ServiceRegistry 

pub struct ServiceRegistry { /* private fields */ }

A generic service registry keyed by TypeId.

Services are stored as Arc<dyn Any + Send + Sync> and can be retrieved by their concrete type via get.

Example

use khora_core::service_registry::ServiceRegistry;

struct MyService { value: i32 }

let mut registry = ServiceRegistry::new();
registry.insert(MyService { value: 42 });

let svc = registry.get::<MyService>().unwrap();
assert_eq!(svc.value, 42);

Implementations

impl ServiceRegistry

pub fn new() -> Self

Creates an empty service registry.

pub fn insert<T: Send + Sync + 'static>(&mut self, service: T)

Inserts a service into the registry, keyed by T’s TypeId.

If a service of the same type was already registered, it is replaced.

pub fn get<T: Send + Sync + 'static>(&self) -> Option<&T>

Retrieves a shared reference to a previously registered service.

Returns None if no service of type T has been registered.

pub fn contains<T: Send + Sync + 'static>(&self) -> bool

Returns true if a service of type T is registered.

pub fn len(&self) -> usize

Returns the number of registered services.

pub fn is_empty(&self) -> bool

Returns true if no services are registered.
