Trait RenderItem 

pub trait RenderItem {
    // Required method
    fn render(
        &self,
        area: Rect,
        frame: &mut Frame<'_>,
        selected: bool,
        skip_rows: u16,
    );

    // Provided method
    fn height(&self) -> u16 { ... }
}

Trait for items that can render themselves.

Implement this trait for item types that should render in a VirtualizedList.

Required Methods

fn render( &self, area: Rect, frame: &mut Frame<'_>, selected: bool, skip_rows: u16, )

Render the item into the frame at the given area.

Arguments

• area - The area to render into.
• frame - The frame to render into.
• selected - Whether the item is selected.
• skip_rows - Number of rows to skip from the top of the item content. This is non-zero when the item partially overlaps the top of the viewport.

Provided Methods

fn height(&self) -> u16

Height of this item in terminal rows.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
