Conditional rendering - Yew

import Tabs from '@theme/Tabs' import TabItem from '@theme/TabItem'

If blocks

To conditionally render some markup, we wrap it in an if block:

rust

use yew::prelude::*;

html! {
    if true {
        <p>{ "True case" }</p>
    }
};

</TabItem> <TabItem value="if - else" label="if - else">

rust

use yew::prelude::*;
let some_condition = true;

html! {
    if some_condition {
        <p>{ "True case" }</p>
    } else {
        <p>{ "False case" }</p>
    }
};

</TabItem> <TabItem value="if let" label="if let">

rust

use yew::prelude::*;
let some_text = Some("text");

html! {
    if let Some(text) = some_text {
        <p>{ text }</p>
    }
};

</TabItem> <TabItem value="if let else" label="if let else">

rust

use yew::prelude::*;
let some_text = Some("text");

html! {
    if let Some(text) = some_text {
        <p>{ text }</p>
    } else {
        <p>{ "False case" }</p>
    }
};

</TabItem> </Tabs>
