VkQueryResultStatusKHR

Specific status codes that can be returned from a query are:

typedef enum VkQueryResultStatusKHR {
    VK_QUERY_RESULT_STATUS_ERROR_KHR = -1,
    VK_QUERY_RESULT_STATUS_NOT_READY_KHR = 0,
    VK_QUERY_RESULT_STATUS_COMPLETE_KHR = 1,
    // Provided by extensions
    VK_QUERY_RESULT_STATUS_INSUFFICIENT_BITSTREAM_BUFFER_RANGE_KHR = 999999000,
} VkQueryResultStatusKHR;

pub struct QueryResultStatusKHR(u32);
impl QueryResultStatusKHR {
    pub const ERROR: Self = -1;
    pub const NOT_READY: Self = 0;
    pub const COMPLETE: Self = 1;
    pub const INSUFFICIENTSTREAM_BUFFER_RANGE: Self = 999999000;
}

• VK_QUERY_RESULT_STATUS_NOT_READY_KHR specifies that the query result is not yet available.
• VK_QUERY_RESULT_STATUS_ERROR_KHR specifies that operations did not complete successfully.
• VK_QUERY_RESULT_STATUS_COMPLETE_KHR specifies that operations completed successfully and the query result is available.
• VK_QUERY_RESULT_STATUS_INSUFFICIENT_BITSTREAM_BUFFER_RANGE_KHR specifies that a video encode operation did not complete successfully due to the destination video bitstream buffer range not being sufficiently large to fit the encoded bitstream data.
