Traits§
- Render
Backend - Opaque render backend trait with downcasting capability. Core crate defines this trait; UI crates downcast to concrete implementations. This enables true backend independence — core compiles without Ratatui.
- Render
Target - Abstraction over the terminal output backend. Uses trait objects (dyn) at the compositor boundary for runtime flexibility. Performance: vtable indirection is dispatched once per frame/window, not per cell.
