Trait Component 

pub trait Component: Send {
    // Required methods
    fn measure(&mut self, width: u16) -> u16;
    fn render(&mut self, area: Rect, buf: &mut Buffer);
    fn handle_event(&mut self, event: &UiEvent) -> EventResult;
    fn invalidate(&mut self);
}

Re-export of the pi-tui component contract for downstream callers. Height-for-width terminal component.

render must emit exactly the number of rows previously returned by Component::measure for the same width.

Required Methods

fn measure(&mut self, width: u16) -> u16

Measure the height required to render at width.

fn render(&mut self, area: Rect, buf: &mut Buffer)

Render into area of buf.

fn handle_event(&mut self, event: &UiEvent) -> EventResult

Handle an input event.

fn invalidate(&mut self)

Drop width/theme-sensitive caches after resize or theme change.

Dyn Compatibility

This trait is dyn compatible.

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