[][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.

Implementations

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>(self, status: T) -> Builder where
    StatusCode: TryFrom<T>,
    <StatusCode as TryFrom<T>>::Error: Into<Error>, 
[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(self, version: Version) -> 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>(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 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 res = Response::builder()
    .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>(self, extension: T) -> 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 extensions_ref(&self) -> Option<&Extensions>[src]

Get a reference to the extensions for this response builder.

If the builder has an error, this returns None.

Example

let req = Response::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 response builder.

If the builder has an error, this returns None.

Example

let mut req = Response::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<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.

Examples


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