Struct trillium_http_types::Request [−][src]
pub struct Request { /* fields omitted */ }Expand description
An HTTP request.
Examples
use http_types::Request; let mut req = Request::get("https://example.com"); req.set_body("Hello, Nori!");
Implementations
Create a new request.
Sets a string representation of the peer address of this request. 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 request was received 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 that information is available for this request.
Get the local socket address for the underlying transport, if that information is available for this request.
Get the remote address for this request.
This is determined in the following priority:
Forwardedheaderforkey- The first
X-Forwarded-Forheader - Peer address of the transport
Get the destination host for this request.
This is determined in the following priority:
Forwardedheaderhostkey- The first
X-Forwarded-Hostheader Hostheader- URL domain, if any
Set the HTTP method.
Get a reference to the url.
Examples
use http_types::{Request, Response, StatusCode}; let mut req = Request::get("https://example.com"); assert_eq!(req.url().scheme(), "https");
Get a mutable reference to the url.
Examples
use http_types::{Method, Request, Response, StatusCode, Url}; let mut req = Request::get("https://example.com"); req.url_mut().set_scheme("http"); assert_eq!(req.url().scheme(), "http");
Set the request body.
Examples
use http_types::{Method, Request}; let mut req = Request::get("https://example.com"); req.set_body("Hello, Nori!");
Swaps the value of the body with another body, without deinitializing either one.
Examples
use http_types::{Body, Method, Request}; let mut req = Request::get("https://example.com"); 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!");
Replace the request body with a new body, and return the old body.
Examples
use http_types::{Body, Request}; let mut req = Request::get("https://example.com"); 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 request body, replacing it with an empty body.
Examples
use http_types::{Body, Request}; let mut req = Request::get("https://example.com"); 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 request. If you want to read the body without
consuming the request, consider using the take_body method and
then calling Body::into_string or using the Request’s AsyncRead
implementation to read the body.
Examples
use async_std::io::Cursor; use http_types::{Body, Request}; let mut req = Request::get("https://example.com"); let cursor = Cursor::new("Hello Nori"); let body = Body::from_reader(cursor, None); req.set_body(body); assert_eq!(&req.body_string().await.unwrap(), "Hello Nori");
Read the body as bytes.
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_bytes or using the Request’s AsyncRead
implementation to read the body.
Examples
use http_types::{Body, Request}; let bytes = vec![1, 2, 3]; let mut req = Request::get("https://example.com"); req.set_body(Body::from_bytes(bytes)); let bytes = req.body_bytes().await?; assert_eq!(bytes, vec![1, 2, 3]);
Read the body as JSON.
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 Request’s AsyncRead
implementation to read the body.
Examples
use http_types::convert::{Deserialize, Serialize}; use http_types::{Body, Request}; #[derive(Debug, Serialize, Deserialize)] struct Cat { name: String, } let cat = Cat { name: String::from("chashu"), }; let mut req = Request::get("https://example.com"); req.set_body(Body::from_json(&cat)?); let cat: Cat = req.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 Request’s AsyncRead
implementation to read the body.
Examples
use http_types::convert::{Deserialize, Serialize}; use http_types::{Body, Request}; #[derive(Debug, Serialize, Deserialize)] struct Cat { name: String, } let cat = Cat { name: String::from("chashu"), }; let mut req = Request::get("https://example.com"); req.set_body(Body::from_form(&cat)?); let cat: Cat = req.body_form().await?; assert_eq!(&cat.name, "chashu");
Get an HTTP header.
Get a mutable reference to a header.
Remove a header.
pub fn insert_header(
&mut self,
name: impl Into<HeaderName>,
values: impl ToHeaderValues
) -> Option<HeaderValues>
pub fn insert_header(
&mut self,
name: impl Into<HeaderName>,
values: impl ToHeaderValues
) -> Option<HeaderValues>Set an HTTP header.
Examples
use http_types::Request; let mut req = Request::get("https://example.com"); 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::Request; let mut req = Request::get("https://example.com"); req.append_header("Content-Type", "text/plain");
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 request has a set body stream length of zero,
false otherwise.
Get the HTTP version, if one has been set.
Examples
use http_types::{Request, Version}; let mut req = Request::get("https://example.com"); assert_eq!(req.version(), None); req.set_version(Some(Version::Http2_0)); assert_eq!(req.version(), Some(Version::Http2_0));
Set the HTTP version.
Examples
use http_types::{Request, Version}; let mut req = Request::get("https://example.com"); req.set_version(Some(Version::Http2_0));
Sends trailers to the a receiver.
Receive trailers from a sender.
Returns true if sending trailers is in progress.

Get the URL querystring.
Examples
use http_types::convert::Deserialize; use http_types::Request; use std::collections::HashMap; #[derive(Deserialize)] struct Index { page: u32, selections: HashMap<String, String>, } let mut req = Request::get("https://httpbin.org/get?page=2&selections[width]=narrow&selections[height]=tall"); let Index { page, selections } = req.query().unwrap(); assert_eq!(page, 2); assert_eq!(selections["width"], "narrow"); assert_eq!(selections["height"], "tall");
Set the URL querystring.
Examples
use http_types::convert::Serialize; use http_types::{Method, Request}; use std::collections::HashMap; #[derive(Serialize)] struct Index { page: u32, topics: Vec<&'static str>, } let query = Index { page: 2, topics: vec!["rust", "crabs", "crustaceans"] }; let mut req = Request::get("https://httpbin.org/get"); req.set_query(&query).unwrap(); assert_eq!(req.url().query(), Some("page=2&topics[0]=rust&topics[1]=crabs&topics[2]=crustaceans"));
Create a GET request.
The GET method requests a representation of the specified resource.
Requests using GET should only retrieve data.
Examples
use http_types::{Method, Request}; let mut req = Request::get("https://example.com"); req.set_body("Hello, Nori!"); assert_eq!(req.method(), Method::Get);
Create a HEAD request.
The HEAD method asks for a response identical to that of a GET
request, but without the response body.
Examples
use http_types::{Method, Request}; let mut req = Request::head("https://example.com"); assert_eq!(req.method(), Method::Head);
Create a POST request.
The POST method is used to submit an entity to the specified resource,
often causing a change in state or side effects on the server.
Examples
use http_types::{Method, Request}; let mut req = Request::post("https://example.com"); assert_eq!(req.method(), Method::Post);
Create a PUT request.
The PUT method replaces all current representations of the target
resource with the request payload.
Examples
use http_types::{Method, Request}; let mut req = Request::put("https://example.com"); assert_eq!(req.method(), Method::Put);
Create a DELETE request.
The DELETE method deletes the specified resource.
Examples
use http_types::{Method, Request}; let mut req = Request::delete("https://example.com"); assert_eq!(req.method(), Method::Delete);
Create a CONNECT request.
The CONNECT method establishes a tunnel to the server identified by
the target resource.
Examples
use http_types::{Method, Request}; let mut req = Request::connect("https://example.com"); assert_eq!(req.method(), Method::Connect);
Create a OPTIONS request.
The OPTIONS method is used to describe the communication options for
the target resource.
Examples
use http_types::{Method, Request}; let mut req = Request::options("https://example.com"); assert_eq!(req.method(), Method::Options);
Create a TRACE request.
The TRACE method performs a message loop-back test along the path to
the target resource.
Examples
use http_types::{Method, Request}; let mut req = Request::trace("https://example.com"); assert_eq!(req.method(), Method::Trace);
Create a PATCH request.
The PATCH method is used to apply partial modifications to a resource.
Examples
use http_types::{Method, Request}; let mut req = Request::patch("https://example.com"); assert_eq!(req.method(), Method::Patch);
