Crate Features

featureOverview
debugEnable extra asserts for debugging nines itself.
unsigned-scalarAllow 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 "unsigned-scalars" feature.
