VkPerformanceCounterUnitKHR

Performance counters have an associated unit. This unit describes how to interpret the performance counter result.

The performance counter unit types which may be returned in VkPerformanceCounterKHR::unit are:

typedef enum VkPerformanceCounterUnitKHR {
    VK_PERFORMANCE_COUNTER_UNIT_GENERIC_KHR = 0,
    VK_PERFORMANCE_COUNTER_UNIT_PERCENTAGE_KHR = 1,
    VK_PERFORMANCE_COUNTER_UNIT_NANOSECONDS_KHR = 2,
    VK_PERFORMANCE_COUNTER_UNIT_BYTES_KHR = 3,
    VK_PERFORMANCE_COUNTER_UNIT_BYTES_PER_SECOND_KHR = 4,
    VK_PERFORMANCE_COUNTER_UNIT_KELVIN_KHR = 5,
    VK_PERFORMANCE_COUNTER_UNIT_WATTS_KHR = 6,
    VK_PERFORMANCE_COUNTER_UNIT_VOLTS_KHR = 7,
    VK_PERFORMANCE_COUNTER_UNIT_AMPS_KHR = 8,
    VK_PERFORMANCE_COUNTER_UNIT_HERTZ_KHR = 9,
    VK_PERFORMANCE_COUNTER_UNIT_CYCLES_KHR = 10,
} VkPerformanceCounterUnitKHR;

pub struct PerformanceCounterUnitKHR(u32);
impl PerformanceCounterUnitKHR {
    pub const GENERIC: Self = 0;
    pub const PERCENTAGE: Self = 1;
    pub const NANOSECONDS: Self = 2;
    pub const BYTES: Self = 3;
    pub const BYTES_PER_SECOND: Self = 4;
    pub const KELVIN: Self = 5;
    pub const WATTS: Self = 6;
    pub const VOLTS: Self = 7;
    pub const AMPS: Self = 8;
    pub const HERTZ: Self = 9;
    pub const CYCLES: Self = 10;
}
