Trait runtime_injector::ServiceFactory

pub trait ServiceFactory<D>: Service {
    type Result: Service;
    fn invoke(
        &mut self, 
        injector: &Injector, 
        request_info: &RequestInfo
    ) -> InjectResult<Self::Result>;
}

A factory for creating instances of a service. All functions of arity 12 or less are automatically service factories if the arguments to that function are valid service requests and the return value is a valid service type.

Type parameters

• D - Tuple of this service’s dependencies.

Example

use runtime_injector::{Injector, RequestInfo, ServiceFactory, Svc};

struct Foo;
struct Bar;

fn factory(foo: Svc<Foo>) -> Bar {
    todo!()
}
let injector: Injector = todo!();
factory.invoke(&injector, &RequestInfo::new());

Associated Types
