Multipart form support for Actix Web.
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
```rust
use actix_web::{post, App, HttpServer, Responder};
use actix_multipart::form::{json::Json as MPJson, tempfile::TempFile, MultipartForm};
use actix_multipart::form::{json::Json as MpJson, tempfile::TempFile, MultipartForm};
use serde::Deserialize;
