Struct hyper::server::response::Response
[−]
[src]
pub struct Response<'a, W: Any = Fresh> { pub version: HttpVersion, // some fields omitted }
The outgoing half for a Tcp connection, created by a Server
and given to a Handler
.
The default StatusCode
for a Response
is 200 OK
.
There is a Drop
implementation for Response
that will automatically
write the head and flush the body, if the handler has not already done so,
so that the server doesn't accidentally leave dangling requests.
Fields
version: HttpVersion
The HTTP version of this response.
Methods
impl<'a, W: Any> Response<'a, W>
[src]
pub fn status(&self) -> StatusCode
[src]
The status of this response.
pub fn headers(&self) -> &Headers
[src]
The headers of this response.
pub fn construct(
version: HttpVersion,
body: HttpWriter<&'a mut (Write + 'a)>,
status: StatusCode,
headers: &'a mut Headers
) -> Response<'a, Fresh>
[src]
version: HttpVersion,
body: HttpWriter<&'a mut (Write + 'a)>,
status: StatusCode,
headers: &'a mut Headers
) -> Response<'a, Fresh>
Construct a Response from its constituent parts.
pub fn deconstruct(
self
) -> (HttpVersion, HttpWriter<&'a mut (Write + 'a)>, StatusCode, &'a mut Headers)
[src]
self
) -> (HttpVersion, HttpWriter<&'a mut (Write + 'a)>, StatusCode, &'a mut Headers)
Deconstruct this Response into its constituent parts.
impl<'a> Response<'a, Fresh>
[src]
pub fn new(
stream: &'a mut (Write + 'a),
headers: &'a mut Headers
) -> Response<'a, Fresh>
[src]
stream: &'a mut (Write + 'a),
headers: &'a mut Headers
) -> Response<'a, Fresh>
Creates a new Response that can be used to write to a network stream.
pub fn send(self, body: &[u8]) -> Result<()>
[src]
Writes the body and ends the response.
This is a shortcut method for when you have a response with a fixed
size, and would only need a single write
call normally.
Example
fn handler(res: Response) { res.send(b"Hello World!").unwrap(); }
The above is the same, but shorter, than the longer:
use std::io::Write; use hyper::header::ContentLength; fn handler(mut res: Response) { let body = b"Hello World!"; res.headers_mut().set(ContentLength(body.len() as u64)); let mut res = res.start().unwrap(); res.write_all(body).unwrap(); }
pub fn start(self) -> Result<Response<'a, Streaming>>
[src]
Consume this Response
pub fn status_mut(&mut self) -> &mut StatusCode
[src]
Get a mutable reference to the status.
pub fn headers_mut(&mut self) -> &mut Headers
[src]
Get a mutable reference to the Headers.
