Trait ViewFn 

pub trait ViewFn<'a, State, Message, Theme, Renderer>
where
    Renderer: Renderer,
{
    // Required method
    fn view(
        &self,
        state: &'a State,
    ) -> impl Widget<Message, Theme, Renderer> + 'a;
}

The view logic of some Application.

This trait allows the application builder to take any closure that returns any widget.

Required Methods

fn view(&self, state: &'a State) -> impl Widget<Message, Theme, Renderer> + 'a

Produces the widget of the Application.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<'a, T, State, Message, Theme, Renderer, W> ViewFn<'a, State, Message, Theme, Renderer> for T
