Struct HullFacts 

pub struct HullFacts {
    pub domain: TessDomain,
    pub partitioning: Partitioning,
    pub topology: TessTopology,
    pub input_control_points: u32,
    pub output_control_points: u32,
    pub max_tess_factor_bits: u32,
    pub patch_constants: Vec<Varying>,
}

What a hull program states about its patch beyond its varyings. The patch-constant varyings are its outputs per patch (SV_TessFactor, SV_InsideTessFactor, whatever the domain program reads); outputs of the interface are its control points’.

Fields

domain: TessDomain

The domain the hull program declares.

partitioning: Partitioning

How the tessellator divides the edges.

topology: TessTopology

What the tessellator outputs.

input_control_points: u32

Control points the program reads per patch (1 to 32).

output_control_points: u32

Control points the program writes per patch (1 to 32).

max_tess_factor_bits: u32

The largest tessellation factor, as the bits of an f32 (the interface is hashed).

patch_constants: Vec<Varying>

The patch-constant outputs, per patch, in the order the signature lists them.
