# `tek_layout`

this crate exposes several layout operators
which work entirely in unsigned coordinates
and are generic over `tek_engine::Engine`
and `tek_engine::Content`. chiefly, they
are not dependent on rendering framework.

* `Fill` is to make the content's dimension equal to the container's.
* `Fixed` is to assign a fixed dimension to its content.
* `Shrink`/`Expand` are to change the dimension of the content
* `Min`/`Max` are to constrain the dimension of the content
* `Push`/`Pull` are to move the content along the axis
* `Margin`/`Padding` are to change the dimension proportionally
* `Align` is to pin the content along the axis of the container
* `When` is to render content conditionally
* `Either` is to alternates between contents
* `Map` is to transform each content
* `Reduce` is to transform all contents into one
* and, finally, `Bsp` is to put 2 where there was 1.

**todo.** and then you're like,
"but why are they generic over E in the first place
and not, say, over E::Unit? that might even free up
some space to implement for non-uint cosmologies...
