impl EntryCustom<Arc<Library>>[src]

pub unsafe fn new() -> Result<Entry, LoadingError>[src]

Load default Vulkan library for the current platform

Safety

dlopening native libraries is inherently unsafe. The safety guidelines for Library::new and Library::get apply here.

use ash::{vk, Entry, version::EntryV1_0};
let entry = Entry::new()?;
let app_info = vk::ApplicationInfo {
    api_version: vk::make_version(1, 0, 0),
    ..Default::default()
};
let create_info = vk::InstanceCreateInfo {
    p_application_info: &app_info,
    ..Default::default()
};
let instance = unsafe { entry.create_instance(&create_info, None)? };

pub unsafe fn with_library(
    path: &impl AsRef<OsStr>
) -> Result<Entry, LoadingError>[src]

Load Vulkan library at path

Safety

dlopening native libraries is inherently unsafe. The safety guidelines for Library::new and Library::get apply here.

Trait Implementations

impl<L: Clone> Clone for EntryCustom<L>[src]

impl<L> EntryV1_0 for EntryCustom<L>[src]

type Instance = Instance

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

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.
