Struct Identity

pub struct Identity { /* private fields */ }

A no-op middleware.

When wrapping a Service, the Identity middleware returns the provided service without modifying it.

Implementations

impl Identity

pub fn new() -> Identity

Create a new Identity value

Trait Implementations

impl<T> Chain<T> for Identity

type Output = Chain<Identity, T>

The combined type

fn chain(self, other: T) -> Self::Output

Combine self with other.

impl Clone for Identity

fn clone(&self) -> Identity

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Identity

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Identity

fn default() -> Identity

Returns the “default value” for a type.

impl<S: Service> Middleware<S> for Identity

Decorates a Service, transforming either the request or the response.

type Request = <S as Service>::Request

The wrapped service request type

type Response = <S as Service>::Response

The wrapped service response type

type Error = <S as Service>::Error

The wrapped service’s error type

type Service = S

The wrapped service

fn wrap(&self, inner: S) -> Self::Service

Wrap the given service with the middleware, returning a new service that has been decorated with the middleware.

fn chain<T>(self, middleware: T) -> Chain<Self, T>

where T: Middleware<Self::Service>, Self: Sized,

Return a new Middleware instance that applies both self and middleware to services being wrapped.
