Trait Implementations

impl<L: Clone> Clone for EntryCustom<L>

fn clone(&self) -> EntryCustom<L>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<L> EntryV1_0 for EntryCustom<L>

type Instance = Instance

unsafe fn create_instance(
    &self,
    create_info: &InstanceCreateInfo,
    allocation_callbacks: Option<&AllocationCallbacks>
) -> Result<Self::Instance, InstanceError>

https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/vkCreateInstance.html

Safety

In order for the created Instance to be valid for the duration of its usage, the Entry this was called on must be dropped later than the resulting Instance.
