Struct Declaration 

pub struct Declaration {
    pub word: usize,
    pub opcode: u16,
    pub control: u32,
    pub kind: Declared,
}

A declaration, typed. word is where it starts.

Fields

word: usize

The word of the token stream the declaration starts at.

opcode: u16

The opcode token’s low 11 bits (see opcode_name).

control: u32

The opcode token’s bits 11 to 23 as stored.

kind: Declared

The declaration, typed.

Implementations

impl Declaration

pub fn global_flags(&self) -> Option<GlobalFlags>

The flags of a dcl_globalFlags declaration; None for any other declaration.

pub fn geometry_input_primitive(&self) -> Option<u32>

pub fn geometry_output_topology(&self) -> Option<u32>

A geometry program’s output topology (dcl_outputtopology; a D3D_PRIMITIVE_TOPOLOGY: 1 point list, 3 line strip, 5 triangle strip).

pub fn max_output_vertex_count(&self) -> Option<u32>

The tessellator partitioning (dcl_tessellator_partitioning; a D3D11_TESSELLATOR_PARTITIONING: 1 integer, 2 pow2, 3 fractional odd, 4 fractional even).

pub fn tessellator_output_primitive(&self) -> Option<u32>

The tessellator output primitive (dcl_tessellator_output_primitive; a D3D11_TESSELLATOR_OUTPUT_PRIMITIVE: 1 point, 2 line, 3 triangle clockwise, 4 triangle counter-clockwise).

pub fn hull_max_tess_factor(&self) -> Option<f32>

A hull program’s largest tessellation factor (dcl_hs_max_tessfactor).

pub fn fork_phase_instance_count(&self) -> Option<u32>

The instance count of a hull program’s fork phase (dcl_hs_fork_phase_instance_count).

pub fn join_phase_instance_count(&self) -> Option<u32>

The instance count of a hull program’s join phase (dcl_hs_join_phase_instance_count).
