Struct BoxCloneSyncService

pub struct BoxCloneSyncService<T, U, E>(/* private fields */);

A Clone + Send + Sync boxed Service.

BoxCloneSyncService turns a service into a trait object, allowing the response future type to be dynamic, and allowing the service to be cloned and shared.

This is similar to BoxCloneService except the resulting service implements Sync.

Implementations

impl<T, U, E> BoxCloneSyncService<T, U, E>

pub fn new<S>(inner: S) -> Self

where S: Service<T, Response = U, Error = E> + Clone + Send + Sync + 'static, S::Future: Send + 'static,

Create a new BoxCloneSyncService.

pub fn layer<S>() -> LayerFn<fn(S) -> Self>

where S: Service<T, Response = U, Error = E> + Clone + Send + Sync + 'static, S::Future: Send + 'static,

Returns a Layer for wrapping a Service in a BoxCloneSyncService middleware.
