MingaEditor.Renderer.Caches (Minga v0.1.0)

Copy Markdown View Source

Explicit render-pipeline cache state, replacing process-dictionary entries.

Each field corresponds to a former Process.put/get key used across the render pipeline stages. Renderer.Server retains the struct across frames and injects it into RenderPipeline.Input; it never crosses back into Editor state.

Ownership by stage

  • Chrome (chrome_prev_*): RenderPipeline, stage 5 fingerprint cache.
  • Content (search_decoration_cache, doc_highlight_cache): consumed by ContentHelpers.build_render_ctx/3; cleared when the fingerprint changes.
  • Emit (last_title, last_window_bg, last_link_cursor): consumed by Frontend.Emit stage 7.
  • Adapter (adapter_gui_caches): core GUI adapter fingerprint state.
