An asynchronous constructor of Services.

Associated Types

type ResBody: Payload

The Payload body of the http::Response.

type Error: Into<Box<dyn StdError + Send + Sync>>

The error type that can be returned by Services.

type Service: Service<ReqBody, ResBody = Self::ResBody, Error = Self::Error>

The resolved Service from make_service().

type Future: Future<Output = Result<Self::Service, Self::MakeError>>

The future returned from new_service of a Service.

type MakeError: Into<Box<dyn StdError + Send + Sync>>

The error type that can be returned when creating a new Service.

Required methods

fn poll_ready(&mut self, cx: &mut Context) -> Poll<Result<(), Self::MakeError>>

Returns Ready when the constructor is ready to create a new Service.

The implementation of this method is allowed to return a Ready even if the factory is not ready to create a new service. In this case, the future returned from make_service will resolve to an error.

fn make_service(&mut self, target: Target) -> Self::Future

Create a new Service.
