        &mut self, 
        boundary: &str,

}

A trait describing an HTTP request that can be used to send multipart data.

Associated Types

type Stream: HttpStream

The HTTP stream type that can be opend by this request, to which the multipart data will be written.

type Error: From<Error> + Into<<Self::Stream as HttpStream>::Error>

The error type for this request. Must be compatible with io::Error as well as Self::HttpStream::Error

Required methods

fn apply_headers(&mut self, boundary: &str, content_len: Option<u64>) -> bool

Set the Content-Type header to multipart/form-data and supply the boundary value. If content_len is given, set the Content-Length header to its value.

Return true if any and all sanity checks passed and the stream is ready to be opened, or false otherwise.

fn open_stream(self) -> Result<Self::Stream, Self::Error>

Open the request stream and return it or any error otherwise.

impl HttpRequest for Request<Fresh>

Feature: hyper

type Stream = Request<Streaming>

type Error = HyperError

fn apply_headers(&mut self, boundary: &str, content_len: Option<u64>) -> bool

Panics

If self.method() != Method::Post.

fn open_stream(self) -> Result<Self::Stream, Self::Error>

impl HttpRequest for ()

type Stream = Sink

type Error = Error

Implementors

impl HttpRequest for ClientRequest

type Stream = HttpBuffer

type Error = Error

fn apply_headers(&mut self, boundary: &str, content_len: Option<u64>) -> bool

fn open_stream(self) -> Result<HttpBuffer, Error>

Panics

If apply_headers() was not called.

impl<R: HttpRequest> HttpRequest for SizedRequest<R> where
    <R::Stream as HttpStream>::Error: From<R::Error>, 

type Stream = Self

type Error = R::Error

fn apply_headers(&mut self, boundary: &str, _content_len: Option<u64>) -> bool

SizedRequest ignores _content_len because it sets its own later.

fn open_stream(self) -> Result<Self, Self::Error>
