Struct BoxedAsyncMakeService

pub struct BoxedAsyncMakeService<S, E> { /* private fields */ }

A type-erased wrapper for asynchronous service factories. A type-erased wrapper for asynchronous service factories.

BoxedAsyncMakeService enables dynamic dispatch for async service factories, allowing for flexible composition of asynchronous service creation pipelines.

Implementations

impl<S, E> BoxedAsyncMakeService<S, E>

pub fn new<AMS>(ams: AMS) -> Self

where AMS: AsyncMakeService<Service = S, Error = E> + Send + Sync + 'static, S: 'static,

pub fn downcast_ref<T: Any>(&self) -> Option<&T>

pub unsafe fn downcast_ref_unchecked<T: Any>(&self) -> &T

Safety

If you are sure the inner type is T, you can downcast it.

Trait Implementations

impl<S, E> AsyncMakeService for BoxedAsyncMakeService<S, E>

type Service = S

The type of service this factory creates.

type Error = E

The type of error that can occur during service creation.

async fn make_via_ref( &self, old: Option<&Self::Service>, ) -> Result<Self::Service, Self::Error>

Asynchronously creates a new service, optionally using an existing service as a reference.

fn make(&self) -> impl Future<Output = Result<Self::Service, Self::Error>>

Asynchronously creates a new service without referencing an existing one.

impl<S, E> Drop for BoxedAsyncMakeService<S, E>

fn drop(&mut self)
