+    const Rect{N,T} = HyperRectangle{N,T}
+
+A rectangle in N dimensions, formally the cartesian product of intervals. See also [`HyperRectangle`](@ref). Its aliases are
+
+|        |`T`(eltype)|`Float32` |`Int`     |
+|--------|-----------|----------|----------|
+|`N`(dim)|`Rect{N,T}`|`Rectf{N}`|`Recti{N}`|
+|`2`     |`Rect2{T}` |`Rect2f`  |`Rect2i`  |
+|`3`     |`Rect3{T}` |`Rect3f`  |`Rect3i`  |
+
+There is an additional unexported alias `RectT` that simply reverses the order of type parameters: `RectT{T,N} == Rect{N,T}`.
