//! Example: Suspense
//! -----------------
//! This example demonstrates how the use_suspense hook can be used to load and render asynchronous data.  Suspense enables
//! components to wait on futures to complete before rendering the result into VNodes. These VNodes are immediately
//! available in a suspended" fashion and will automatically propogate to the UI when the future completes.
//!
//! Currently, suspense futures are non-restartable. In the future, we'll provide more granular control of how to start,
//! stop, and reset these futures.
