rama::http::service::web::response

Struct AppendHeaders

pub struct AppendHeaders<I>(pub I);
Expand description

Append headers to a response.

Returning something like [("content-type", "foo=bar")] from a handler will override any existing content-type headers. If instead you want to append headers, use AppendHeaders:

use rama_http_types::header::SET_COOKIE;
use rama_http::service::web::response::{AppendHeaders, IntoResponse};

async fn handler() -> impl IntoResponse {
    // something that sets the `set-cookie` header
    let set_some_cookies = /* ... */

    (
        set_some_cookies,
        // append two `set-cookie` headers to the response
        // without overriding the ones added by `set_some_cookies`
        AppendHeaders([
            (SET_COOKIE, "foo=bar"),
            (SET_COOKIE, "baz=qux"),
        ])
    )
}
