Struct http_types::Response[][src]

pub struct Response { /* fields omitted */ }
Expand description

An HTTP response.

Examples

use http_types::{Response, StatusCode};

let mut res = Response::new(StatusCode::Ok);
res.set_body("Hello, Nori!");

Implementations

Create a new response.

Get the status

Get a mutable reference to a header.

Get an HTTP header.

Remove a header.

Set an HTTP header.

Examples

use http_types::{Method, Response, StatusCode, Url};

let mut req = Response::new(StatusCode::Ok);
req.insert_header("Content-Type", "text/plain");

Append a header to the headers.

Unlike insert this function will not override the contents of a header, but insert a header if there aren’t any. Or else append to the existing list of headers.

Examples

use http_types::{Response, StatusCode};

let mut res = Response::new(StatusCode::Ok);
res.append_header("Content-Type", "text/plain");

Set the body reader.

Examples

use http_types::{Response, StatusCode};

let mut res = Response::new(StatusCode::Ok);
res.set_body("Hello, Nori!");

Replace the response body with a new body, returning the old body.

Examples

use http_types::{Body, Method, Response, StatusCode, Url};

let mut req = Response::new(StatusCode::Ok);
req.set_body("Hello, Nori!");

let mut body: Body = req.replace_body("Hello, Chashu");

let mut string = String::new();
body.read_to_string(&mut string).await?;
assert_eq!(&string, "Hello, Nori!");

Swaps the value of the body with another body, without deinitializing either one.

Examples

use http_types::{Body, Method, Response, StatusCode, Url};

let mut req = Response::new(StatusCode::Ok);
req.set_body("Hello, Nori!");

let mut body = "Hello, Chashu!".into();
req.swap_body(&mut body);

let mut string = String::new();
body.read_to_string(&mut string).await?;
assert_eq!(&string, "Hello, Nori!");

Take the response body, replacing it with an empty body.

Examples

use http_types::{Body, Method, Response, StatusCode, Url};

let mut req = Response::new(StatusCode::Ok);
req.set_body("Hello, Nori!");
let mut body: Body = req.take_body();

let mut string = String::new();
body.read_to_string(&mut string).await?;
assert_eq!(&string, "Hello, Nori!");

Read the body as a string.

This consumes the response. If you want to read the body without consuming the response, consider using the take_body method and then calling Body::into_string or using the Response’s AsyncRead implementation to read the body.

Examples

use async_std::io::Cursor;
use http_types::{Body, Method, Response, StatusCode, Url};

let mut res = Response::new(StatusCode::Ok);
let cursor = Cursor::new("Hello Nori");
let body = Body::from_reader(cursor, None);
res.set_body(body);
assert_eq!(&res.body_string().await.unwrap(), "Hello Nori");

Read the body as bytes.

This consumes the Response. If you want to read the body without consuming the response, consider using the take_body method and then calling Body::into_bytes or using the Response’s AsyncRead implementation to read the body.

Examples

use http_types::{Body, Method, Response, StatusCode, Url};

let bytes = vec![1, 2, 3];
let mut res = Response::new(StatusCode::Ok);
res.set_body(Body::from_bytes(bytes));

let bytes = res.body_bytes().await?;
assert_eq!(bytes, vec![1, 2, 3]);

Read the body as JSON.

This consumes the response. If you want to read the body without consuming the response, consider using the take_body method and then calling Body::into_json or using the Response’s AsyncRead implementation to read the body.

Examples

use http_types::convert::{Deserialize, Serialize};
use http_types::{Body, Method, Response, StatusCode, Url};

#[derive(Debug, Serialize, Deserialize)]
struct Cat {
    name: String,
}

let cat = Cat {
    name: String::from("chashu"),
};
let mut res = Response::new(StatusCode::Ok);
res.set_body(Body::from_json(&cat)?);

let cat: Cat = res.body_json().await?;
assert_eq!(&cat.name, "chashu");

Read the body as x-www-form-urlencoded.

This consumes the request. If you want to read the body without consuming the request, consider using the take_body method and then calling Body::into_json or using the Response’s AsyncRead implementation to read the body.

Examples

use http_types::convert::{Deserialize, Serialize};
use http_types::{Body, Method, Response, StatusCode, Url};

#[derive(Debug, Serialize, Deserialize)]
struct Cat {
    name: String,
}

let cat = Cat {
    name: String::from("chashu"),
};
let mut res = Response::new(StatusCode::Ok);
res.set_body(Body::from_form(&cat)?);

let cat: Cat = res.body_form().await?;
assert_eq!(&cat.name, "chashu");

Set the response MIME.

Get the current content type

Get the length of the body stream, if it has been set.

This value is set when passing a fixed-size object into as the body. E.g. a string, or a buffer. Consumers of this API should check this value to decide whether to use Chunked encoding, or set the response length.

Returns true if the set length of the body stream is zero, false otherwise.

Get the HTTP version, if one has been set.

Examples

use http_types::{Response, StatusCode, Version};

let mut res = Response::new(StatusCode::Ok);
assert_eq!(res.version(), None);

res.set_version(Some(Version::Http2_0));
assert_eq!(res.version(), Some(Version::Http2_0));

Sets a string representation of the peer address that this response was sent to. This might take the form of an ip/fqdn and port or a local socket address.

Sets a string representation of the local address that this response was sent on. This might take the form of an ip/fqdn and port, or a local socket address.

Get the peer socket address for the underlying transport, if appropriate

Get the local socket address for the underlying transport, if appropriate

Set the HTTP version.

Examples

use http_types::{Response, StatusCode, Version};

let mut res = Response::new(StatusCode::Ok);
res.set_version(Some(Version::Http2_0));

Set the status.

Sends trailers to the a receiver.

Receive trailers from a sender.

Returns true if sending trailers is in progress.

This is supported on unstable only.

Sends an upgrade connection to the a receiver.

This is supported on unstable only.

Receive an upgraded connection from a sender.

This is supported on unstable only.

Returns true if a protocol upgrade is in progress.

An iterator visiting all header pairs in arbitrary order.

An iterator visiting all header pairs in arbitrary order, with mutable references to the values.

An iterator visiting all header names in arbitrary order.

An iterator visiting all header values in arbitrary order.

Returns a reference to the existing local.

Returns a mutuable reference to the existing local state.

Examples

use http_types::{Response, StatusCode, Version};

let mut res = Response::new(StatusCode::Ok);
res.ext_mut().insert("hello from the extension");
assert_eq!(res.ext().get(), Some(&"hello from the extension"));
