[][src]Struct http::request::Builder

pub struct Builder { /* fields omitted */ }

An HTTP request builder

This type can be used to construct an instance or Request through a builder-like pattern.

Methods

impl Builder[src]

pub fn new() -> Builder[src]

Creates a new default instance of Builder to construct a Request.

Examples

let req = request::Builder::new()
    .method("POST")
    .body(())
    .unwrap();

pub fn method<T>(&mut self, method: T) -> &mut Builder where
    Method: HttpTryFrom<T>, 
[src]

Set the HTTP method for this request.

This function will configure the HTTP method of the Request that will be returned from Builder::build.

By default this is GET.

Examples

let req = Request::builder()
    .method("POST")
    .body(())
    .unwrap();

pub fn method_ref(&self) -> Option<&Method>[src]

Get the HTTP Method for this request.

By default this is GET. if builder has error, returns None.

Examples

 
let mut req = Request::builder();
assert_eq!(req.method_ref(),Some(&Method::GET));
req.method("POST");
assert_eq!(req.method_ref(),Some(&Method::POST));
req.method("DELETE");
assert_eq!(req.method_ref(),Some(&Method::DELETE));

pub fn uri<T>(&mut self, uri: T) -> &mut Builder where
    Uri: HttpTryFrom<T>, 
[src]

Set the URI for this request.

This function will configure the URI of the Request that will be returned from Builder::build.

By default this is /.

Examples

let req = Request::builder()
    .uri("https://www.rust-lang.org/")
    .body(())
    .unwrap();

pub fn uri_ref(&self) -> Option<&Uri>[src]

Get the URI for this request

By default this is /

Examples

 
let mut req = Request::builder();
assert_eq!(req.uri_ref().unwrap().to_string(), "/" );
req.uri("https://www.rust-lang.org/");
assert_eq!(req.uri_ref().unwrap().to_string(), "https://www.rust-lang.org/" );

pub fn version(&mut self, version: Version) -> &mut Builder[src]

Set the HTTP version for this request.

This function will configure the HTTP version of the Request that will be returned from Builder::build.

By default this is HTTP/1.1

Examples

let req = Request::builder()
    .version(Version::HTTP_2)
    .body(())
    .unwrap();

pub fn header<K, V>(&mut self, key: K, value: V) -> &mut Builder where
    HeaderName: HttpTryFrom<K>,
    HeaderValue: HttpTryFrom<V>, 
[src]

Appends a header to this request builder.

This function will append the provided key/value as a header to the internal HeaderMap being constructed. Essentially this is equivalent to calling HeaderMap::append.

Examples

let req = Request::builder()
    .header("Accept", "text/html")
    .header("X-Custom-Foo", "bar")
    .body(())
    .unwrap();

pub fn headers_ref(&self) -> Option<&HeaderMap<HeaderValue>>[src]

Get header on this request builder. when builder has error returns None

Example

let mut req = Request::builder();
req.header("Accept", "text/html")
   .header("X-Custom-Foo", "bar");
let headers = req.headers_ref().unwrap();
assert_eq!( headers["Accept"], "text/html" );
assert_eq!( headers["X-Custom-Foo"], "bar" );

pub fn headers_mut(&mut self) -> Option<&mut HeaderMap<HeaderValue>>[src]

Get header on this request builder. when builder has error returns None

Example

let mut req = Request::builder();
{
  let headers = req.headers_mut().unwrap();
  headers.insert("Accept", HeaderValue::from_static("text/html"));
  headers.insert("X-Custom-Foo", HeaderValue::from_static("bar"));
}
let headers = req.headers_ref().unwrap();
assert_eq!( headers["Accept"], "text/html" );
assert_eq!( headers["X-Custom-Foo"], "bar" );

pub fn extension<T>(&mut self, extension: T) -> &mut Builder where
    T: Any + Send + Sync + 'static, 
[src]

Adds an extension to this builder

Examples

let req = Request::builder()
    .extension("My Extension")
    .body(())
    .unwrap();

assert_eq!(req.extensions().get::<&'static str>(),
           Some(&"My Extension"));

pub fn body<T>(&mut self, body: T) -> Result<Request<T>>[src]

"Consumes" this builder, using the provided body to return a constructed Request.

Errors

This function may return an error if any previously configured argument failed to parse or get converted to the internal representation. For example if an invalid head was specified via header("Foo", "Bar\r\n") the error will be returned when this function is called rather than when header was called.

Panics

This method will panic if the builder is reused. The body function can only be called once.

Examples

let request = Request::builder()
    .body(())
    .unwrap();
