Trait Responder 

pub trait Responder {
    // Required method
    fn response_to(self, req: &RequestContext<'_, '_>) -> Response<ResponseBody>;
}

A trait for types that can be converted into HTTP responses.

Types implementing this trait can be returned directly from request handlers and will be automatically converted into HTTP responses.

Required Methods

fn response_to(self, req: &RequestContext<'_, '_>) -> Response<ResponseBody>

Implementations on Foreign Types

impl Responder for &'static str

Implementation for static strings returns them as plain text responses.

fn response_to(self, _req: &RequestContext<'_, '_>) -> Response<ResponseBody>

impl Responder for Infallible

fn response_to(self, _req: &RequestContext<'_, '_>) -> Response<ResponseBody>

impl Responder for ParseError

Responder implementation for ParseError to convert parsing errors to responses

fn response_to(self, req: &RequestContext<'_, '_>) -> Response<ResponseBody>

impl Responder for ()

Implementation for unit type () returns an empty response.

fn response_to(self, _req: &RequestContext<'_, '_>) -> Response<ResponseBody>

impl Responder for String

Implementation for String returns it as a plain text response.

fn response_to(self, _req: &RequestContext<'_, '_>) -> Response<ResponseBody>

impl<B> Responder for Response<B>

where B: Into<ResponseBody>,

Implementation for Response allows passing through pre-built responses. The response body is converted to the internal ResponseBody type.

fn response_to(self, _req: &RequestContext<'_, '_>) -> Response<ResponseBody>

impl<T: Responder> Responder for (StatusCode, T)

Implementation for (StatusCode, T) tuple allows setting a status code along with the response content.

fn response_to(self, req: &RequestContext<'_, '_>) -> Response<ResponseBody>

impl<T: Responder> Responder for (T, StatusCode)

Implementation for (T, StatusCode) tuple - same as above but with reversed order.

fn response_to(self, req: &RequestContext<'_, '_>) -> Response<ResponseBody>

impl<T: Responder> Responder for Option<T>

Implementation for Option allows handlers to return Option types. None case returns an empty response.

fn response_to(self, req: &RequestContext<'_, '_>) -> Response<ResponseBody>

impl<T: Responder> Responder for Box<T>

Implementation for Box allows boxing responders.

fn response_to(self, req: &RequestContext<'_, '_>) -> Response<ResponseBody>

impl<T: Responder, E: Responder> Responder for Result<T, E>

Implementation for Result allows handlers to return Result types directly. The Ok and Err variants must both implement Responder.

fn response_to(self, req: &RequestContext<'_, '_>) -> Response<ResponseBody>

Implementors

impl Responder for NotFound

impl<S> Responder for SseStream<S>

where S: Stream<Item = Event> + Send + 'static,
