//! # Actix Form Data
//! A library for retrieving form data from Actix Web's multipart streams. It can stream
//! uploaded files onto the filesystem (its main purpose), but it can also parse associated
//! form data.
//!
//! # Example
//!
//!```rust
//! use actix_form_data::{Error, Field, Form, FormData, Multipart, Value};
//! use actix_web::{
//! web::{post, resource},
//! App, HttpRequest, HttpResponse, HttpServer,
//! };
//! use futures_util::stream::StreamExt;
//!
//! struct UploadedContent(Value<()>);
//!
//! impl FormData for UploadedContent {
//! type Item = ();
//! type Error = Error;
//!
//! fn form(_: &HttpRequest) -> Result<Form<Self::Item, Self::Error>, Self::Error> {
//! Ok(Form::new()
//! .field("Hey", Field::text())
//! .field(
//! "Hi",
//! Field::map()
//! .field("One", Field::int())
//! .field("Two", Field::float())
//! .finalize(),
//! )
//! .field(
//! "files",
//! Field::array(Field::file(|_, _, mut stream| async move {
//! while let Some(res) = stream.next().await {
//! res?;
//! }
//! Ok(()) as Result<(), Error>
//! })),
//! ))
//! }
//!
//! fn extract(value: Value<Self::Item>) -> Result<Self, Self::Error>
//! where
//! Self: Sized,
//! {
//! Ok(UploadedContent(value))
//! }
//! }
//!
//! async fn upload(Multipart(UploadedContent(value)): Multipart<UploadedContent>) -> HttpResponse {
//! println!("Uploaded Content: {:#?}", value);
//! HttpResponse::Created().finish()
//! }
//!
//! #[actix_rt::main]
//! async fn main() -> Result<(), anyhow::Error> {
//! HttpServer::new(move || App::new().service(resource("/upload").route(post().to(upload))))
//! .bind("127.0.0.1:8080")?
//! .run();
//! // .await?;
//!
//! Ok(())
//! }
//!```
