Struct Variant 

pub struct Variant {
    pub group: usize,
    pub blob_index: u32,
    pub keywords: Vec<String>,
    pub gpu_program_type: i64,
    pub requirements: i64,
    pub parameter_blob: Option<u32>,
    pub parameters: Option<Parameters>,
}

One compiled variant: the blob entry holding its code, its keywords, its GPU program type (Unity’s ShaderGpuProgramType: 17 a D3D11 pixel program before 2021.2, 18 an SM 5.0 one after) and its shader requirements mask; group is the index of the player sub-program list it is in (from 2021.2) or its hardware tier (before); parameters its own, where the player stores them per variant (before 2021.2), else None: the pass’s.

Fields

group: usize

The index of the player sub-program list the variant is in (2021.2 on), or its hardware tier (before).

blob_index: u32

The entry of the platform’s blob that holds the variant’s program record.

keywords: Vec<String>

The keywords the variant is compiled with.

gpu_program_type: i64

Unity’s ShaderGpuProgramType.

requirements: i64

The shader requirements mask.

parameter_blob: Option<u32>

The blob entry holding this variant’s own parameters, where the player stores them there (from 2021.2: m_ParameterBlobIndices, parallel to the sub-program lists).

parameters: Option<Parameters>

The variant’s own parameters, where the player stores them per variant (before 2021.2); None: the pass program’s.
