//! Example: Spread pattern for Components
//! --------------------------------------
//!
//! Dioxus supports the "spread" pattern for manually building a component's properties. This is useful when props
//! are passed down from a parent, or it's more ergonomic to construct props from outside the rsx! macro.
//!
//! To use the spread pattern, simply pass ".." followed by a Rust expression. This pattern also supports overriding
//! values, using the manual props as the base and then modifying fields specified with non-spread attributes.
