Struct TextureRead

    pub word: usize,
    pub opcode: u16,

    pub texture_indexed: bool,

}

One instruction of a program that reads a texture (a shader resource view, t<n>).

Fields

word: usize

The instruction’s first word in the token stream.

opcode: u16

The instruction’s opcode (see crate::opcode_name).

texture: u32

The number of the t register, or the constant part of its index where TextureRead::texture_indexed. In Shader Model 5.1 the register of the declared range the instruction reads, as fxc’s disassembly gives it.

texture_indexed: bool

The texture register is indexed by a register (t[r1.x + 3]).

texture_space: Option<u32>

The texture’s register space: 0 before Shader Model 5.1; in 5.1 its declaration’s, None where the program declares no texture of the id the instruction names.

sampler: Option<u32>

The number of the s register the instruction samples with; none for a load, which uses no sampler.

sampler_indexed: bool

The sampler register is indexed by a register.

sampler_space: Option<u32>

The sampler’s register space, as TextureRead::texture_space gives the texture’s; none without a sampler.

comparison: bool

The instruction compares the sampled value with a reference (sample_c, sample_c_lz, gather4_c, gather4_po_c and the feedback forms of them).

sampler_mode: Option<u32>

How the program declares the sampler (dcl_sampler): 0 default, 1 comparison, 2 mono; none where the program declares no sampler of that number (or the instruction has no sampler).
