Struct vulkano::device::QueueFamilyProperties

#[non_exhaustive]
pub struct QueueFamilyProperties {
    pub queue_flags: QueueFlags,
    pub queue_count: u32,
    pub timestamp_valid_bits: Option<u32>,
    pub min_image_transfer_granularity: [u32; 3],
}

Properties of a queue family in a physical device.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

queue_flags: QueueFlags

Attributes of the queue family.

queue_count: u32

The number of queues available in this family.

This guaranteed to be at least 1 (or else that family wouldn’t exist).

timestamp_valid_bits: Option<u32>

If timestamps are supported, the number of bits supported by timestamp operations. The returned value will be in the range 36..64.

If timestamps are not supported, this is None.

min_image_transfer_granularity: [u32; 3]

The minimum granularity supported for image transfers, in terms of [width, height, depth].
