# Multipart [](https://travis-ci.org/abonander/multipart) [](https://crates.io/crates/multipart)
Client- and server-side abstractions for HTTP file uploads (POST requests with `Content-Type: multipart/form-data`).
Supports several different (**sync**hronous API) HTTP crates.
**Async**hronous (i.e. `futures`-based) API support will be provided by [multipart-async].
Minimum supported Rust version: 1.22.1*
* only `mock`, `client` and `server` features, only guaranteed to compile
Fully tested Rust version: 1.26.1
### [Documentation](http://docs.rs/multipart/)
## Integrations
Example files demonstrating how to use `multipart` with these crates are available under [`examples/`](examples).
### [Hyper ](https://crates.io/crates/hyper)
via the `hyper` feature (enabled by default).
**Note: Hyper 0.9, 0.10 (synchronous API) only**; support for asynchronous APIs will be provided by [multipart-async].
Client integration includes support for regular `hyper::client::Request` objects via `multipart::client::Multipart`, as well
as integration with the new `hyper::Client` API via `multipart::client::lazy::Multipart` (new in 0.5).
Server integration for `hyper::server::Request` via `multipart::server::Multipart`.
### [Iron ](https://crates.io/crates/iron)
via the `iron` feature.
Provides regular server-side integration with `iron::Request` via `multipart::server::Multipart`,
as well as a convenient `BeforeMiddleware` implementation in `multipart::server::iron::Intercept`.
### [Nickel ](https://crates.io/crates/nickel) <sup>returning to `multipart` in 0.14!</sup>
via the `nickel` feature.
Provides server-side integration with `&mut nickel::Request` via `multipart::server::Multipart`.
### [tiny_http ](https://crates.io/crates/tiny_http)
via the `tiny_http` feature.
Provides server-side integration with `tiny_http::Request` via `multipart::server::Multipart`.
### [Rocket ](https://crates.io/crates/rocket)
Direct integration is not provided as the Rocket folks seem to want to handle `multipart/form-data`
behind the scenes which would supercede any integration with `multipart`. However, an example is available
showing how to use `multipart` on a Rocket server: [examples/rocket.rs](examples/rocket.rs)

### [buf_redux ](https://crates.io/crates/buf_redux)
Customizable drop-in `std::io::BufReader` replacement, created to be used in this crate.
Needed because it can read more bytes into the buffer without the buffer being empty, necessary
when a boundary falls across two reads. (It was easier to author a new crate than try to get this added
to `std::io::BufReader`.)
### [httparse ](https://crates.io/crates/httparse)
Fast, zero-copy HTTP header parsing, used to read field headers in `multipart/form-data` request bodies.
### [twoway ](https://crates.io/crates/twoway)
Fast string and byte-string search. Used to find boundaries in the request body. SSE 4.2 acceleration available
under the `sse42` or `twoway/pcmp` features.
