VkShaderInstrumentationMetricDataHeaderARM

The shader instrumentation metrics block header is defined as:

typedef struct VkShaderInstrumentationMetricDataHeaderARM {
    uint32_t resultIndex;
    uint32_t resultSubIndex;
    VkShaderStageFlags stages;
    uint32_t basicBlockIndex;
} VkShaderInstrumentationMetricDataHeaderARM;

pub struct ShaderInstrumentationMetricDataHeaderARM {
    result_index: u32,
    result_sub_index: u32,
    stages: vk::ShaderStageFlags,
    basic_block_index: u32,
}

• resultIndex is the result index of the metric block, as captured when the command was recorded.
• resultSubIndex is a secondary index with the result index, explained further below.
• stages is a bitfield of VkShaderStageFlagBits describing the shader stages that the metric block is for.
• basicBlockIndex is the index of the basic block within the shader that the metric block is for.
