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

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.

Implementations

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>(self, method: T) -> Builder where
    Method: TryFrom<T>,
    <Method as TryFrom<T>>::Error: Into<Error>, 
[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 = req.method("POST");
assert_eq!(req.method_ref(),Some(&Method::POST));

pub fn uri<T>(self, uri: T) -> Builder where
    Uri: TryFrom<T>,
    <Uri as TryFrom<T>>::Error: Into<Error>, 
[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(), "/" );

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

pub fn version(self, version: Version) -> 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>(self, key: K, value: V) -> Builder where
    HeaderName: TryFrom<K>,
    <HeaderName as TryFrom<K>>::Error: Into<Error>,
    HeaderValue: TryFrom<V>,
    <HeaderValue as TryFrom<V>>::Error: Into<Error>, 
[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 req = Request::builder()
    .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 headers 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>(self, extension: T) -> 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 extensions_ref(&self) -> Option<&Extensions>[src]

Get a reference to the extensions for this request builder.

If the builder has an error, this returns None.

Example

let req = Request::builder().extension("My Extension").extension(5u32);
let extensions = req.extensions_ref().unwrap();
assert_eq!(extensions.get::<&'static str>(), Some(&"My Extension"));
assert_eq!(extensions.get::<u32>(), Some(&5u32));

pub fn extensions_mut(&mut self) -> Option<&mut Extensions>[src]

Get a mutable reference to the extensions for this request builder.

If the builder has an error, this returns None.

Example

let mut req = Request::builder().extension("My Extension");
let mut extensions = req.extensions_mut().unwrap();
assert_eq!(extensions.get::<&'static str>(), Some(&"My Extension"));
extensions.insert(5u32);
assert_eq!(extensions.get::<u32>(), Some(&5u32));

pub fn body<T>(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.

Examples


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