Expand description

Macro-defined layout

This trait is a copy of Layout, implemented by the #[layout] macro. In some cases it is useful to invoke kas::MacroDefinedLayout::set_rect (or other method) from the corresponding Layout method to perform some other action before using the default implementation.

[#[layout]]: kas::layout
