Struct leptos::ErrorBoundaryProps

pub struct ErrorBoundaryProps<F, IV>where
    F: Fn(Scope, RwSignal<Errors>) -> IV + 'static,
    IV: IntoView,{
    pub children: Children,
    pub fallback: F,
}

Props for the ErrorBoundary component.

When you render a Result<_, _> in your view, in the Err case it will render nothing, and search up through the view tree for an <ErrorBoundary/>. This component lets you define a fallback that should be rendered in that error case, allowing you to handle errors within a section of the interface.

let (value, set_value) = create_signal(cx, Ok(0));
let on_input = move |ev| set_value(event_target_value(&ev).parse::<i32>());

view! { cx,
  <input type="text" on:input=on_input/>
  <ErrorBoundary
    fallback=move |_, _| view! { cx, <p class="error">"Enter a valid number."</p>}
  >
    <p>"Value is: " {value}</p>
  </ErrorBoundary>
}

Required Props

• cx: Scope
• children: Children
  • The components inside the tag which will get rendered
• fallback: [F]
  • A fallback that will be shown if an error occurs.

Fields

children: Children

The components inside the tag which will get rendered

fallback: F

A fallback that will be shown if an error occurs.

Implementations

impl<F, IV> ErrorBoundaryProps<F, IV>where F: Fn(Scope, RwSignal<Errors>) -> IV + 'static, IV: IntoView,

pub fn builder() -> ErrorBoundaryPropsBuilder<F, IV, ((), ())>

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