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();

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();

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();

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();

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"));

"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();
