VkPushConstantRange

The VkPushConstantRange structure is defined as:

typedef struct VkPushConstantRange {
    VkShaderStageFlags stageFlags;
    uint32_t offset;
    uint32_t size;
} VkPushConstantRange;

pub struct PushConstantRange {
    stage_flags: vk::ShaderStageFlags, // Which stages use the range
    offset: u32, // Start of the range, in bytes
    size: u32, // Size of the range, in bytes
}

• stageFlags is a set of stage flags describing the shader stages that will access a range of push constants. If a particular stage is not included in the range, then accessing members of that range of push constants from the corresponding shader stage will return undefined values.
• offset and size are the start offset and size, respectively, consumed by the range. Both offset and size are in units of bytes and must be a multiple of 4. The layout of the push constant variables is specified in the shader.
