Struct SignatureElement 

pub struct SignatureElement {
    pub name: String,
    pub index: u32,
    pub system_value: u32,
    pub component_type: u32,
    pub register: u32,
    pub mask: u8,
    pub read_write_mask: u8,
    pub at: usize,
    pub stream: u32,
    pub min_precision: u32,
}

One element of a signature as stored.

Fields

name: String

The semantic name (POSITION, TEXCOORD, …).

index: u32

The semantic index (the 1 of TEXCOORD1).

system_value: u32

D3D_NAME.

component_type: u32

D3D_REGISTER_COMPONENT_TYPE.

register: u32

The register the element is packed into.

mask: u8

The components the element occupies, one bit each (x is bit 0).

read_write_mask: u8

The components a program reads (inputs) or never writes (outputs), as stored.

at: usize

Where the record starts, in words of the chunk.

stream: u32

The output stream of a geometry program’s element (OSG5, OSG1); 0 in the other layouts.

min_precision: u32

D3D_MIN_PRECISION (ISG1, OSG1, PSG1); 0 (default) in the other layouts.

Implementations

impl SignatureElement

pub fn system_value_for(&self, output: bool, kind: ProgramType) -> u32

The element’s D3D_NAME: as stored, but for a pixel program’s outputs, which store none; theirs is the one their semantic names (SV_Target is 64, SV_Depth 65, …). output says which signature the element is in.

pub fn system_value_name(&self, output: bool, kind: ProgramType) -> String

Self::system_value_for as Microsoft’s disassembler names it in the SysValue column (POS, TARGET; SV and the number for one it has no name for).

pub fn format_name(&self) -> &'static str

The component type as Microsoft’s disassembler names it in the Format column, or the minimum precision where the element has one (float, min16f).
