Crate Features
| feature | Overview |
|---|---|
| debug | Enable extra asserts for debugging nines itself. |
| unsigned-scalar | Allow Scalar to use underflow-prone uNN types. |
Structs
| Axises | A { horizontal, vertical } pair. |
| Dimensions | The dimensions of a nine-square layout. See also ValidDimensions. |
| Error | A generic nines error. Currently opaque by design. |
| Layout | Describe a layout to render with. You'll probably start with a: |
| Rect | A rectangle. See also ValidRect. Generally not inclusive of the right/bottom edge. |
| Style | The scaling style of a nine-square layout. |
| ValidDimensions | Slice dimensions with non-negative & non-NAN dimensions (including borders.) |
| ValidRect | A rectangle with non-negative & non-NAN dimensions. |
Enums
| Scale | How to scale images. Based roughly off of the CSS3 border-image-repeat property values. |
Traits
| Scalar | iNN or fNN intrinsics. Opt-in to underflow-prone uNN support via |
