[][src]Struct http::response::Builder

pub struct Builder { /* fields omitted */ }

An HTTP response builder

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

Methods

impl Builder[src]

pub fn new() -> Builder[src]

Creates a new default instance of Builder to construct either a Head or a Response.

Examples


let response = response::Builder::new()
    .status(200)
    .body(())
    .unwrap();

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

Set the HTTP status for this response.

This function will configure the HTTP status code of the Response that will be returned from Builder::build.

By default this is 200.

Examples


let response = Response::builder()
    .status(200)
    .body(())
    .unwrap();

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

Set the HTTP version for this response.

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

By default this is HTTP/1.1

Examples


let response = Response::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 response 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 response = Response::builder()
    .header("Content-Type", "text/html")
    .header("X-Custom-Foo", "bar")
    .header("content-length", 0)
    .body(())
    .unwrap();

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

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

Example

let mut res = Response::builder();
res.header("Accept", "text/html")
   .header("X-Custom-Foo", "bar");
let headers = res.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 response builder. when builder has error returns None

Example

let mut res = Response::builder();
{
  let headers = res.headers_mut().unwrap();
  headers.insert("Accept", HeaderValue::from_static("text/html"));
  headers.insert("X-Custom-Foo", HeaderValue::from_static("bar"));
}
let headers = res.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 response = Response::builder()
    .extension("My Extension")
    .body(())
    .unwrap();

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

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

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

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 response = Response::builder()
    .body(())
    .unwrap();
