//! # 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 std::path::PathBuf;
//!
//! use actix_multipart::Multipart;
//! use actix_web::{
//! web::{post, resource, Data},
//! App, HttpResponse, HttpServer,
//! };
//! use form_data::{handle_multipart, Error, Field, FilenameGenerator, Form};
//! use futures::Future;
//!
//! struct Gen;
//!
//! impl FilenameGenerator for Gen {
//! fn next_filename(&self, _: &mime::Mime) -> Option<PathBuf> {
//! let mut p = PathBuf::new();
//! p.push("examples/filename.png");
//! Some(p)
//! }
//! }
//!
//! fn upload((mp, state): (Multipart, Data<Form>)) -> Box<Future<Item = HttpResponse, Error = Error>> {
//! Box::new(
//! handle_multipart(mp, state.get_ref().clone()).map(|uploaded_content| {
//! println!("Uploaded Content: {:?}", uploaded_content);
//! HttpResponse::Created().finish()
//! }),
//! )
//! }
//!
//! fn main() -> Result<(), failure::Error> {
//! let form = 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(Gen)));
//!
//! println!("{:?}", form);
//!
//! HttpServer::new(move || {
//! App::new()
//! .data(form.clone())
//! .service(resource("/upload").route(post().to(upload)))
//! })
//! .bind("127.0.0.1:8080")?;
//! // .run()?;
//!
//! Ok(())
//! }
//!```
