dioxus/examples/spread.rs

//! This example demonstrates how to use the spread operator to pass attributes to child components.
//!
//! This lets components like the `Link` allow the user to extend the attributes of the underlying `a` tag.
//! These attributes are bundled into a `Vec<Attribute>` which can be spread into the child component using the `..` operator.
