The `#[function_component]` attribute also works with generic functions for creating generic components.
|
|
|
|
```rust
|
|
use std::fmt::Display;
|
|
use yew::{function_component, html, Properties, Html};
|
|
|
|
#[derive(Properties, PartialEq)]
|
|
pub struct Props<T>
|
|
where
|
|
T: PartialEq,
|
|
{
|
|
data: T,
|
|
}
|
|
|
|
#[function_component]
|
|
pub fn MyGenericComponent<T>(props: &Props<T>) -> Html
|
|
where
|
|
T: PartialEq + Display,
|
|
{
|
|
html! {
|
|
<p>
|
|
{ &props.data }
|
|
</p>
|
|
}
|
|
}
|
|
|
|
// then can be used like this
|
|
html! {
|
|
<MyGenericComponent<i32> data=123 />
|
|
};
|
|
|
|
// or
|
|
html! {
|
|
<MyGenericComponent<String> data={"foo".to_string()} />
|
|
};
|
|
```
