ClosureRoot

oxi::tui::v2_bridge

Struct ClosureRoot 

Source 
pub struct ClosureRoot { /* private fields */ }
Expand description

Temporary adapter that wraps a legacy render closure as a Renderable.

The content hash changes every frame because legacy rendering is not memoizable. Remove this adapter once the legacy widgets have migrated to native Renderable implementations.

Implementations§

Source§

impl ClosureRoot

Source

pub fn new<F>(render_fn: F) -> Self
where F: FnMut(&mut Frame<'_>) + 'static,

Creates an adapter around a legacy frame-rendering closure.

Trait Implementations§

Source§

impl Renderable for ClosureRoot

Source§

fn content_hash(&self) -> u64

Hash of the widget’s content. Change this when output would change. Must be deterministic and cheap.
Source§

fn height_for(&self, _width: u16, _ctx: &RenderCtx<'_, '_>) -> u16

Height this widget will occupy at the given width. Used by parents to lay out children, and by scrollback virtualization to skip off-screen widgets entirely.
Source§

fn render(&mut self, _area: Rect, ctx: &mut RenderCtx<'_, '_>)

Paint into area of ctx’s buffer. Only called when content_hash changed since the last frame (or on first frame, or after resize).
