1// @generated — do not edit by hand.
2//! Handler trait for [`FunctionHandler`].
3//!
4//! Implement this trait to provide a custom backend for this service, then mount the
5//! generated handler functions (in the sibling `server` module) onto an `axum::Router`
6//! with your implementation as state.
7//!
8//! # Composability
9//!
10//! A single struct can implement multiple handler traits to serve multiple
11//! services. Use [`axum::Router::merge`] to compose per-service routers together.
12//!
13//! Manage User-Defined Functions (UDFs) in the service.
