tengri/output/README.md

tengri_output is an abstract interface layout framework.

it expresses the following notions:

• space: Direction, Coordinate, Area, Size, Measure

• output: Out, Draw, Content

  • the layout operators are generic over Draw and/or Content
  • the traits Draw and Content are generic over Out
  • implement Out to bring a layout to a new backend: see TuiOut in tengri_tui

• layout:

  • conditionals: When, Either
  • iteration: Map
  • concatenation: Bsp
  • positioning: Align, Push, Pull
  • sizing: Fill, Fixed, Expand, Shrink, Min, Max
  • implement custom components (that may be backend-dependent): see tui_content in tengri_tui
