+// Super explicit first paragraph because this shows up at the top level and
+// trips up people who are just looking for basic Serialize / Deserialize
+// documentation.
+//
+/// Helper macro when implementing the `Deserializer` part of a new data format
+/// for Serde.
+///
+/// Some [`Deserializer`] implementations for self-describing formats do not
+/// care what hint the [`Visitor`] gives them, they just want to blindly call
+/// the [`Visitor`] method corresponding to the data they can tell is in the
+/// input. This requires repetitive implementations of all the [`Deserializer`]
+/// trait methods.
+///
+/// ```edition2021
+/// # use serde::forward_to_deserialize_any;
+/// # use serde::de::{value, Deserializer, Visitor};
+/// #
+/// # struct MyDeserializer;
+/// #
+/// # impl<'de> Deserializer<'de> for MyDeserializer {
+/// #     type Error = value::Error;
+/// #
+/// #     fn deserialize_any<V>(self, _: V) -> Result<V::Value, Self::Error>
+/// #     where
+/// #         V: Visitor<'de>,
+/// #     {
+/// #         unimplemented!()
+/// #     }
+/// #
+/// #[inline]
+/// fn deserialize_bool<V>(self, visitor: V) -> Result<V::Value, Self::Error>
+/// where
+///     V: Visitor<'de>,
+/// {
+///     self.deserialize_any(visitor)
+/// }
+/// #
+/// #     forward_to_deserialize_any! {
+/// #         i8 i16 i32 i64 i128 u8 u16 u32 u64 u128 f32 f64 char str string
+/// #         bytes byte_buf option unit unit_struct newtype_struct seq tuple
+/// #         tuple_struct map struct enum identifier ignored_any
+/// #     }
+/// # }
+/// ```
+///
+/// The `forward_to_deserialize_any!` macro implements these simple forwarding
+/// methods so that they forward directly to [`Deserializer::deserialize_any`].
+/// You can choose which methods to forward.
+///
+/// ```edition2021
+/// # use serde::forward_to_deserialize_any;
+/// # use serde::de::{value, Deserializer, Visitor};
+/// #
+/// # struct MyDeserializer;
+/// #
+/// impl<'de> Deserializer<'de> for MyDeserializer {
+/// #   type Error = value::Error;
+/// #
+///     fn deserialize_any<V>(self, visitor: V) -> Result<V::Value, Self::Error>
+///     where
+///         V: Visitor<'de>,
+///     {
+///         /* ... */
+/// #       let _ = visitor;
+/// #       unimplemented!()
+///     }
+///
+///     forward_to_deserialize_any! {
+///         bool i8 i16 i32 i64 i128 u8 u16 u32 u64 u128 f32 f64 char str string
+///         bytes byte_buf option unit unit_struct newtype_struct seq tuple
+///         tuple_struct map struct enum identifier ignored_any
+///     }
+/// }
+/// ```
+///
+/// The macro assumes the convention that your `Deserializer` lifetime parameter
+/// is called `'de` and that the `Visitor` type parameters on each method are
+/// called `V`. A different type parameter and a different lifetime can be
+/// specified explicitly if necessary.
+///
+/// ```edition2021
+/// # use serde::forward_to_deserialize_any;
+/// # use serde::de::{value, Deserializer, Visitor};
+/// # use std::marker::PhantomData;
+/// #
+/// # struct MyDeserializer<V>(PhantomData<V>);
+/// #
+/// # impl<'q, V> Deserializer<'q> for MyDeserializer<V> {
+/// #     type Error = value::Error;
+/// #
+/// #     fn deserialize_any<W>(self, visitor: W) -> Result<W::Value, Self::Error>
+/// #     where
+/// #         W: Visitor<'q>,
+/// #     {
+/// #         unimplemented!()
+/// #     }
+/// #
+/// forward_to_deserialize_any! {
+///     <W: Visitor<'q>>
+///     bool i8 i16 i32 i64 i128 u8 u16 u32 u64 u128 f32 f64 char str string
+///     bytes byte_buf option unit unit_struct newtype_struct seq tuple
+///     tuple_struct map struct enum identifier ignored_any
+/// }
+/// # }
