02 · Behavior

What the mounted story proves

  1. 01

    TreeTable

    Representative 120×40 terminal state.

  2. 02

    Passive paint

    No keyboard or pointer action is claimed by this representative story.

  3. 03

    Evidence stays explicit

    3 covered · 9 partial · 5 missing axes.

03 · Implement

Install, then start from exact code

Install

cargo add termrock --git https://github.com/tailrocks/termrock.git --rev 5283c2acf9154d0cfcd37b1ffe821c00faf90ea2

Add TermRock once. Keep domain effects in the host application.

Advanced guidance

Authored implementation guidance

Purpose. Hierarchy plus multi-column metadata without ambiguous Left/Right behavior. Host projects a flattened visible-expanded window; TermRock owns indent, disclosure, sticky headers, selection, and outcomes.

Use Tree for single-column trees and DataTable for flat grids.

ScrollHorizontal scroll only

Anatomy

gutter · sticky header · indent + disclosure + primary · data columns · group bands · aggregate rows (= marker) · footer (nav: mode)

Ownership boundary

TermRock owns reusable terminal rendering and interaction state. The host owns domain data, policy, persistence, authorization, and side effects.

Evidence status

3 covered, 9 partial, and 5 missing contract axes. Missing evidence is not a behavior claim.
