Enum actix_web::Either

pub enum Either<A, B> {
    A(A),
    B(B),
}

Combines two different responder types into a single type

use actix_web::{Either, Error, HttpResponse};

type RegisterResult =
    Either<HttpResponse, Box<Future<Item = HttpResponse, Error = Error>>>;

fn index() -> RegisterResult {
    if is_a_variant() {
        // <- choose left variant
        Either::A(HttpResponse::BadRequest().body("Bad data"))
    } else {
        Either::B(
            // <- Right variant
            Box::new(ok(HttpResponse::Ok()
                .content_type("text/html")
                .body("Hello!")))
        )
    }
}

Trait Implementations

impl<A, B> Responder for Either<A, B> where
    A: Responder,
    B: Responder, 

type Error = Error

The associated error which can be returned.

type Future = EitherResponder<<A::Future as IntoFuture>::Future, <B::Future as IntoFuture>::Future>

The future response value.

fn respond_to(self, req: &HttpRequest) -> Self::Future

Convert itself to AsyncResult or Error.

impl<A: PartialEq, B: PartialEq> PartialEq<Either<A, B>> for Either<A, B>

fn eq(&self, other: &Either<A, B>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Either<A, B>) -> bool

This method tests for !=.
