Struct Cookie 

pub struct Cookie<T, N> {
    pub value: T,
    /* private fields */
}

Cookie value extractor.

Extracts a single cookie value from the Cookie request header using a type-safe name marker.

Example

use fastapi_core::{Cookie, CookieName};

struct SessionId;
impl CookieName for SessionId {
    const NAME: &'static str = "session_id";
}

async fn get_session(Cookie(session): Cookie<String, SessionId>) -> impl IntoResponse {
    format!("Session: {}", session)
}

Fields

value: T

The extracted cookie value.
