Struct AppLayout 

pub struct AppLayout {
    pub header: Rect,
    pub chat: Rect,
    pub side_panel: Rect,
    pub skills: Rect,
    pub memory: Rect,
    pub resources: Rect,
    pub subagents: Rect,
    pub activity: Rect,
    pub input: Rect,
    pub status: Rect,
}

Pre-computed layout rectangles for all regions of the TUI dashboard.

Call compute once per render frame; pass the result to individual widget renderers so each widget knows its exact screen region without re-running the layout algorithm.

When the terminal is narrower than 80 columns or show_side_panels is false, all side-panel fields are set to Rect::default() (zero-sized) and the chat area expands to fill the full width.

Examples

use ratatui::layout::Rect;
use zeph_tui::layout::AppLayout;

let area = Rect::new(0, 0, 120, 40);
let layout = AppLayout::compute(area, true, 3);
assert_eq!(layout.header.height, 1);
assert_eq!(layout.status.height, 1);
assert!(layout.chat.width > layout.side_panel.width);

Fields

header: Rect

Single-row header bar (model name, session info).

chat: Rect

Main chat / transcript area.

side_panel: Rect

Combined side-panel column (zero when hidden).

skills: Rect

Skills mini-panel within the side column.

memory: Rect

Memory mini-panel within the side column.

resources: Rect

MCP resources mini-panel within the side column.

subagents: Rect

Sub-agents mini-panel within the side column.

activity: Rect

Single-row activity / status-spinner bar.

input: Rect

Multi-row text input box.

status: Rect

Single-row bottom status bar (metrics, keybinding hints).

Implementations

impl AppLayout

pub fn compute(area: Rect, show_side_panels: bool, input_height: u16) -> Self

Compute the layout for the given terminal area.

Arguments

• area — the full terminal rect (from Frame::area()).
• show_side_panels — false hides the side panels regardless of width.
• input_height — requested composer height including borders.

Examples

use ratatui::layout::Rect;
use zeph_tui::layout::AppLayout;

// Wide terminal: side panels visible.
let layout = AppLayout::compute(Rect::new(0, 0, 120, 40), true, 3);
assert!(layout.side_panel.width > 0);

// Narrow terminal: side panels hidden.
let layout = AppLayout::compute(Rect::new(0, 0, 60, 24), true, 3);
assert_eq!(layout.side_panel.width, 0);
