Trait actix_service::Transform

pub trait Transform<S> {
    type Request;
    type Response;
    type Error;
    type Transform: Service<Request = Self::Request, Response = Self::Response, Error = Self::Error>;
    type InitError;
    type Future: Future<Output = Result<Self::Transform, Self::InitError>>;
    fn new_transform(&self, service: S) -> Self::Future;
}

The Transform trait defines the interface of a Service factory. Transform is often implemented for middleware, defining how to construct a middleware Service. A Service that is constructed by the factory takes the Service that follows it during execution as a parameter, assuming ownership of the next Service.

Associated Types

type Request

Requests handled by the service.

type Response

type Error

type Transform: Service<Request = Self::Request, Response = Self::Response, Error = Self::Error>

The TransformService value created by this factory

type InitError

Errors produced while building a service.

type Future: Future<Output = Result<Self::Transform, Self::InitError>>

The future response value.
