Trait Component 

pub trait Component {
    // Required method
    fn render<W: Write>(
        &self,
        writer: &mut W,
        ctx: &RenderContext,
        rng: &mut ThreadRng,
    ) -> Result<()>;
}

A self-rendering UI element.

Each component owns its visual state (positions, reveal progress, etc.) and knows how to draw itself into a terminal writer. The wizard loop acts as a thin compositor, calling render on each component in z-order.

Required Methods

fn render<W: Write>( &self, writer: &mut W, ctx: &RenderContext, rng: &mut ThreadRng, ) -> Result<()>

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.
