[][src]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, Result<HttpResponse, Error>>;

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