//! # Support for `TypedMultipart<T>` and `BaseMultipart<T, R>` from `axum_typed_multipart`
//!
//! ## Feature
//!
//! Enable the `typed_multipart` feature to use `Valid<TypedMultipart<T>>` and `Valid<BaseMultipart<T, R>>`.
//!
//! ## Usage
//!
//! 1. Implement `TryFromMultipart` and `Validate` for your data type `T`.
//! 2. In your handler function, use `Valid<TypedMultipart<T>>` or `Valid<BaseMultipart<T, E>` as some parameter's type.
//!
//! ## Example
//!
//! ```no_run
//! #[cfg(feature = "validator")]
//! mod validator_example {
//! use axum::routing::post;
//! use axum::Router;
//! use axum_typed_multipart::{BaseMultipart, TryFromMultipart, TypedMultipart, TypedMultipartError};
//! use axum_valid::Valid;
//! use validator::Validate;
//!
//! pub fn router() -> Router {
//! Router::new()
//! .route("/typed_multipart", post(handler))
//! .route("/base_multipart", post(base_handler))
//! }
//!
//! async fn handler(Valid(TypedMultipart(parameter)): Valid<TypedMultipart<Parameter>>) {
//! assert!(parameter.validate().is_ok());
//! // Support automatic dereferencing
//! println!("v0 = {}, v1 = {}", parameter.v0, parameter.v1);
//! }
//!
//! async fn base_handler(
//! Valid(BaseMultipart {
//! data: parameter, ..
//! }): Valid<BaseMultipart<Parameter, TypedMultipartError>>,
//! ) {
//! assert!(parameter.validate().is_ok());
//! }
//!
//! #[derive(TryFromMultipart, Validate)]
//! struct Parameter {
//! #[validate(range(min = 5, max = 10))]
//! v0: i32,
//! #[validate(length(min = 1, max = 10))]
//! v1: String,
//! }
//! }
//!
//! #[cfg(feature = "garde")]
//! mod garde_example {
//! use axum::routing::post;

//! assert!(parameter.validate(&()).is_ok());
//! // Support automatic dereferencing
