//! Multipart request & form support for Actix Web.
//!
//! The [`Multipart`] extractor aims to support all kinds of `multipart/*` requests, including
//! `multipart/form-data`, `multipart/related` and `multipart/mixed`. This is a lower-level
//! extractor which supports reading [multipart fields](Field), in the order they are sent by the
//! client.
//!
//! Due to additional requirements for `multipart/form-data` requests, the higher level
//! [`MultipartForm`] extractor and derive macro only supports this media type.
//!
//! # Examples
//!
//! ```no_run
//! use actix_web::{post, App, HttpServer, Responder};
//!
//! use actix_multipart::form::{json::Json as MpJson, tempfile::TempFile, MultipartForm};
//! use serde::Deserialize;
//!
//! #[derive(Debug, Deserialize)]
//! struct Metadata {
//!     name: String,
//! }
//!
//! #[derive(Debug, MultipartForm)]
//! struct UploadForm {
//!     #[multipart(limit = "100MB")]
//!     file: TempFile,
//!     json: MpJson<Metadata>,
//! }
//!
//! #[post("/videos")]
//! pub async fn post_video(MultipartForm(form): MultipartForm<UploadForm>) -> impl Responder {
//!     format!(
//!         "Uploaded file {}, with size: {}",
//!         form.json.name, form.file.size
//!     )
//! }
//!
//! #[actix_web::main]
//! async fn main() -> std::io::Result<()> {
//!     HttpServer::new(move || App::new().service(post_video))
//!         .bind(("127.0.0.1", 8080))?
//!         .run()
//!         .await
//! }
//! ```
//!
//! cURL request:
//!
//! ```sh
//! curl -v --request POST \
//!   --url http://localhost:8080/videos \
//!   -F 'json={"name": "Cargo.lock"};type=application/json' \
//!   -F file=@./Cargo.lock
//! ```
//!
//! [`MultipartForm`]: struct@form::MultipartForm
