panes-ratatui 0.5.0

You computed layout rectangles with float precision. Now you need them as ratatui::layout::Rect without gaps between adjacent panels.

panes-ratatui converts panes layouts into ratatui rects with pixel-perfect edge rounding.

Install

cargo add panes panes-ratatui

Usage

use panes::Layout;

let resolved = Layout::master_stack(["editor", "chat", "status"])
    .resolve(80.0, 24.0)?;

let rects = panes_ratatui::convert(&resolved);

for (pid, rect) in &rects {
    // rect is ratatui::layout::Rect { x, y, width, height } — all u16
    frame.render_widget(my_widget, *rect);
}

Adjacent panels sharing a float boundary produce matching integer edges. No gaps, no overlaps.

Focus-aware iteration

focused_panels pairs each entry with a bool indicating focus. A panel is focused when its id matches the given PanelId, or when it is a decoration panel whose content kind matches the focused panel's kind.

for (entry, is_focused) in panes_ratatui::focused_panels(&resolved, runtime.focused()) {
    let style = if is_focused { focused_style } else { normal_style };
    frame.render_widget(styled_block(entry.kind, style), entry.rect);
}

focused_panels_at adds origin offset for nested layouts.
