Function ash::prelude::read_into_uninitialized_vector
source ยท pub(crate) unsafe fn read_into_uninitialized_vector<N: Copy + Default + TryInto<usize>, T>(
f: impl Fn(&mut N, *mut T) -> Result,
) -> VkResult<Vec<T>>
Expand description
Repeatedly calls f
until it does not return vk::Result::INCOMPLETE
anymore, ensuring all
available data has been read into the vector.
See for example vkEnumerateInstanceExtensionProperties
: the number of available items may
change between calls; vk::Result::INCOMPLETE
is returned when the count increased (and the
vector is not large enough after querying the initial size), requiring Ash to try again.
