+
+/// Declares that a function is a [server function](dioxus_fullstack). This means that
+/// its body will only run on the server, i.e., when the `ssr` feature is enabled.
+///
+/// If you call a server function from the client (i.e., when the `csr` or `hydrate` features
+/// are enabled), it will instead make a network request to the server.
+///
+/// You can specify one, two, or three arguments to the server function:
+/// 1. **Required**: A type name that will be used to identify and register the server function
+///   (e.g., `MyServerFn`).
+/// 2. *Optional*: A URL prefix at which the function will be mounted when it’s registered
+///   (e.g., `"/api"`). Defaults to `"/"`.
+/// 3. *Optional*: either `"Cbor"` (specifying that it should use the binary `cbor` format for
+///   serialization), `"Url"` (specifying that it should be use a URL-encoded form-data string).
+///   Defaults to `"Url"`. If you want to use this server function to power a `<form>` that will
+///   work without WebAssembly, the encoding must be `"Url"`. If you want to use this server function
+///   using Get instead of Post methods, the encoding must be `"GetCbor"` or `"GetJson"`.
+///
+/// The server function itself can take any number of arguments, each of which should be serializable
+/// and deserializable with `serde`. Optionally, its first argument can be a [DioxusServerContext](https::/docs.rs/dioxus-fullstack/latest/dixous_server/prelude/struct.DioxusServerContext.html),
+/// which will be injected *on the server side.* This can be used to inject the raw HTTP request or other
+/// server-side context into the server function.
+///
+/// ```ignore
+/// # use dioxus_fullstack::prelude::*; use serde::{Serialize, Deserialize};
+/// # #[derive(Serialize, Deserialize)]
+/// # pub struct Post { }
+/// #[server(ReadPosts, "/api")]
+/// pub async fn read_posts(how_many: u8, query: String) -> Result<Vec<Post>, ServerFnError> {
+///   // do some work on the server to access the database
+///   todo!()
+/// }
+/// ```
+///
+/// Note the following:
+/// - You must **register** the server function by calling `T::register()` somewhere in your main function.
+/// - **Server functions must be `async`.** Even if the work being done inside the function body
+///   can run synchronously on the server, from the client’s perspective it involves an asynchronous
+///   function call.
+/// - **Server functions must return `Result<T, ServerFnError>`.** Even if the work being done
+///   inside the function body can’t fail, the processes of serialization/deserialization and the
+///   network call are fallible.
+/// - **Return types must implement [`Serialize`](https://docs.rs/serde/latest/serde/trait.Serialize.html).**
+///   This should be fairly obvious: we have to serialize arguments to send them to the server, and we
+///   need to deserialize the result to return it to the client.
+/// - **Arguments must be implement [`Serialize`](https://docs.rs/serde/latest/serde/trait.Serialize.html)
+///   and [`DeserializeOwned`](https://docs.rs/serde/latest/serde/de/trait.DeserializeOwned.html).**
+///   They are serialized as an `application/x-www-form-urlencoded`
+///   form data using [`serde_urlencoded`](https://docs.rs/serde_urlencoded/latest/serde_urlencoded/) or as `application/cbor`
+///   using [`cbor`](https://docs.rs/cbor/latest/cbor/).
+/// - **The [DioxusServerContext](https::/docs.rs/dioxus-fullstack/latest/dixous_server/prelude/struct.DioxusServerContext.html) comes from the server.** Optionally, the first argument of a server function
+///   can be a [DioxusServerContext](https::/docs.rs/dioxus-fullstack/latest/dixous_server/prelude/struct.DioxusServerContext.html). This scope can be used to inject dependencies like the HTTP request
+///   or response or other server-only dependencies, but it does *not* have access to reactive state that exists in the client.
