Rust
//! 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.
