 //! - Create a trait with the service handlers.
 //!     - Handlers can accept zero or one parameter and return a [`Result`].
 //!     - The type of the input parameter of the handler needs to implement [`Serialize`](crate::serde::Deserialize) and [`Deserialize`](crate::serde::Deserialize). See [`crate::serde`].
-//!     - The Result contains the return value or a [`HandlerError`][crate::errors::HandlerError], which can be a [`TerminalError`] or any other Rust's `StdError`.

 //!     - The service handler can now be called at `<RESTATE_INGRESS_URL>/MyService/myHandler`. You can optionally override the handler name used via `#[name = "myHandler"]`. More details on handler invocations can be found in the [docs](https://docs.restate.dev/invoke/http).
 //! - Implement the trait on a struct. The struct will contain the actual implementation of the handlers.
 //! - The first parameter of a handler after `&self` is always a [`Context`](crate::context::Context) to interact with Restate.
