Struct ResponseMut 

pub struct ResponseMut<'a> { /* private fields */ }

Mutable response wrapper for setting headers and cookies.

This is the extractor type that handlers receive. Mutations made through this wrapper are stored in request extensions and applied after the handler returns.

Example

use fastapi_core::extract::ResponseMut;

async fn handler(mut resp: ResponseMut) -> &'static str {
    resp.header("X-Powered-By", "fastapi-rust");
    resp.cookie("visited", "true");
    "Hello"
}
