Struct leptos::ShowProps

pub struct ShowProps<W>
where
    W: Fn() -> bool + 'static,
{
    pub children: ChildrenFn,
    pub when: W,
    pub fallback: ViewFn,
}

Props for the Show component.

A component that will show its children when the when condition is true, and show the fallback when it is false, without rerendering every time the condition changes.

The fallback prop is optional and defaults to rendering nothing.

let (value, set_value) = create_signal(0);

view! {
  <Show
    when=move || value.get() < 5
    fallback=|| view! {  "Big number!" }
  >
    "Small number!"
  </Show>
}

Required Props

• children: ChildrenFn
  • The children will be shown whenever the condition in the when closure returns true.
• when: [W]
  • A closure that returns a bool that determines whether this thing runs

Optional Props

• fallback: impl Into<ViewFn>
  • A closure that returns what gets rendered if the when statement is false. By default this is the empty view.

Fields

children: ChildrenFn

The children will be shown whenever the condition in the when closure returns true.

when: W

A closure that returns a bool that determines whether this thing runs

fallback: ViewFn

A closure that returns what gets rendered if the when statement is false. By default this is the empty view.

Implementations

impl<W> ShowProps<W>

where W: Fn() -> bool + 'static,

pub fn builder() -> ShowPropsBuilder<W, ((), (), ())>

Create a builder for building ShowProps. On the builder, call .children(...), .when(...), .fallback(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of ShowProps.

Trait Implementations

impl<W> IntoView for ShowProps<W>

where W: Fn() -> bool + 'static,

fn into_view(self) -> View

Converts the value into View.
