+///
+/// ```
+/// use actix_multipart::form::{tempfile::TempFile, text::Text, MultipartForm};
+///
+/// #[derive(MultipartForm)]
+/// struct ImageUpload {
+///     description: Text<String>,
+///     timestamp: Text<i64>,
+///     image: TempFile,
+/// }
+/// ```
+///
+/// # Optional and List Fields
+///
+/// You can also use `Vec<T>` and `Option<T>` provided that `T: FieldReader`.
+///
+/// A [`Vec`] field corresponds to an upload with multiple parts under the [same field
+/// name](https://www.rfc-editor.org/rfc/rfc7578#section-4.3).
+///
+/// ```
+/// use actix_multipart::form::{tempfile::TempFile, text::Text, MultipartForm};
+///
+/// #[derive(MultipartForm)]
+/// struct Form {
+///     category: Option<Text<String>>,
+///     files: Vec<TempFile>,
+/// }
+/// ```
+///
+/// # Field Renaming
+///
+/// You can use the `#[multipart(rename = "foo")]` attribute to receive a field by a different name.
+///
+/// ```
+/// use actix_multipart::form::{tempfile::TempFile, MultipartForm};

+/// #[derive(MultipartForm)]
+/// struct Form {
+///     #[multipart(rename = "files[]")]
+///     files: Vec<TempFile>,
+/// }
+/// ```
+///
+/// # Field Limits
+///
+/// You can use the `#[multipart(limit = "<size>")]` attribute to set field level limits. The limit
+/// string is parsed using [parse_size].
+///
+/// Note: the form is also subject to the global limits configured using `MultipartFormConfig`.
+///
+/// ```
+/// use actix_multipart::form::{tempfile::TempFile, text::Text, MultipartForm};
+///
+/// #[derive(MultipartForm)]
+/// struct Form {
+///     #[multipart(limit = "2 KiB")]

+/// #[derive(MultipartForm)]
+/// #[multipart(deny_unknown_fields)]

+/// # Duplicate Fields
+///
+/// The behaviour for when multiple fields with the same name are received can be changed using the
+/// `#[multipart(duplicate_field = "<behavior>")]` attribute:
+///
+/// - "ignore": (default) Extra fields are ignored. I.e., the first one is persisted.
+/// - "deny": A `MultipartError::UnsupportedField` error response is returned.
+/// - "replace": Each field is processed, but only the last one is persisted.
+///
+/// Note that `Vec` fields will ignore this option.

-/// # Examples
-/// The [module-level documentation](self) has an example of virtual hosting using `Host` guards.
-///
-/// The example below additionally guards on the host URI's scheme. This could allow routing to
-/// different handlers for `http:` vs `https:` visitors; to redirect, for example.
-/// ```
-/// use actix_web::{web, guard::Host, HttpResponse};
-///
-/// web::scope("/admin")
-///     .guard(Host("admin.rust-lang.org").scheme("https"))
-///     .default_service(web::to(|| async {
-///         HttpResponse::Ok().body("admin connection is secure")
-///     }));
-/// ```
-///
-/// The `Host` guard can be used to set up some form of [virtual hosting] within a single app.
-/// Overlapping scope prefixes are usually discouraged, but when combined with non-overlapping guard
-/// definitions they become safe to use in this way. Without these host guards, only routes under
-/// the first-to-be-defined scope would be accessible. You can test this locally using `127.0.0.1`
-/// and `localhost` as the `Host` guards.
-/// ```
-/// use actix_web::{web, http::Method, guard, App, HttpResponse};
-///
-/// App::new()
-///     .service(
-///         web::scope("")
-///             .guard(guard::Host("www.rust-lang.org"))
-///             .default_service(web::to(|| async {
-///                 HttpResponse::Ok().body("marketing site")
-///             })),
-///     )
-///     .service(
-///         web::scope("")
-///             .guard(guard::Host("play.rust-lang.org"))
-///             .default_service(web::to(|| async {
-///                 HttpResponse::Ok().body("playground frontend")
-///             })),
-///     );
