Http Response

Fields§

§status: Status

Response status code

§data: ResponseBody

Response Data. Can be either a Static Vec or a Stream (impl Read)

§headers: Headers

List of response headers. This does not contain the default headers.

§reason: Option<String>

Response reason phrase. If this is None, the reason phrase will be automatically generated based on the status code.

§close: bool

Force Close Connection. Will set the Connection header to close and will close the connection after the response is sent.

Implementations§

source§

impl Response

pub fn reason(self, reason: impl AsRef<str>) -> Self

Manually set the Reason Phrase. If this is not set, it will be inferred from the status code. Non standard status codes will have a reason phrase of “OK”.

// Create Response
let response = Response::new()
    .status(Status::Ok)
    .reason("Hello");
source

pub fn text(self, text: impl Display) -> Self

Add text as data to a Response. Will accept any type that implements Display, such as String, str, i32, serde_json::Value, etc. This response type is considered static and will be sent in one go, not chunked.

Example
// Create Response
let response = Response::new()
   .text("Hello from afire!");

Add a stream as data to a Response. This response type is considered dynamic and will be streamed to the client in chunks using Transfer-Encoding: chunked.

Example
const PATH: &str = "path/to/file.txt";
let mut server = Server::<()>::new("localhost", 8080);

server.route(Method::GET, "/download-stream", |_| {
    let stream = File::open(PATH).unwrap();
    Response::new().stream(stream)
});

pub fn header(self, key: impl Into<HeaderType>, value: impl AsRef<str>) -> Self

Add a Header to a Response. Will accept any type that implements AsRef, so String, str, &str, etc.

Example
// Create Response
let response = Response::new()
   .header("Test-Header", "Test-Value");

pub fn headers(self, headers: &[Header]) -> Self

Add a list of Headers to a Response. Only accepts a slice of Headers.

Example
// Create Response
let response = Response::new()
    .headers(&[
        Header::new("Content-Type", "text/html"),
        Header::new("Test-Header", "Test-Value")
    ]);
source

pub fn close(self) -> Self

Will set the Connection: close header on the Response. Then it will close the connection after the Response has been sent.

Example
// Create Response
let response = Response::new()
  .text("goodbye!")
  .close();
source

pub fn cookie(self, cookie: SetCookie) -> Self

Add a cookie to a response. The SetCookie will be converted to a Header and added to the Response.

Example
// Create Response and add cookie
let response = Response::new()
    .cookie(SetCookie::new("name", "value"))
    .cookie(SetCookie::new("name2", "value2"));
source

pub fn cookies(self, cookie: &[SetCookie]) -> Self

Add a list of cookies to a response.

Example
// Create Response and add cookie
let response = Response::new()
    .cookies(&[
        SetCookie::new("name", "value"),
        SetCookie::new("name2", "value2")
    ]);
source

pub fn content(self, content_type: Content<'_>) -> Self

Set a Content Type on a Response with a Content enum. This will add a Content-Type header to the Response.

Example
// Create Response and type
let response = Response::new()
    .content(Content::HTML);
