mini_service_locator
mini_service_locator
provides a simple thread-safe service locator: a container that
stores "service" objects of different types, allowing for retrieval of a service by its type.
Example
use mini_service_locator::ServiceLocator;
struct MyUsefulService {
some_shared_thing: i32
}
let mut locator = ServiceLocator::default();
// Put a MyUsefulService into the locator.
locator.provide(MyUsefulService { some_shared_thing: 24 });
// Later, we can fetch this service.
// If we *don't* use store the resulting service as `mut`, we won't be allowed to write to it.
// We can run get<MyUsefulService> multiple times, and it will always provide the same service.
let mut useful_service = locator.get::<MyUsefulService>().unwrap();
assert_eq!(useful_service.read().some_shared_thing, 24);
useful_service.write().some_shared_thing = 32;
assert_eq!(useful_service.read().some_shared_thing, 32);
