Struct Instance 

pub struct Instance {
    pub raw: Arc<RawInstance>,
    pub extensions: Vec<&'static CStr>,
    pub entry: Entry,
}

Fields

raw: Arc<RawInstance>

extensions: Vec<&'static CStr>

Supported extensions of this instance.

entry: Entry

Implementations

impl Instance

pub fn create_surface_from_xlib( &self, dpy: *mut Display, window: Window, ) -> Surface

pub fn create_surface_from_xcb( &self, connection: *mut xcb_connection_t, window: xcb_window_t, ) -> Surface

pub fn create_surface_from_wayland( &self, display: *mut c_void, surface: *mut c_void, ) -> Surface

pub fn create_surface_from_vk_surface_khr(&self, surface: SurfaceKHR) -> Surface

impl Instance

pub fn required_extensions( entry: &Entry, driver_api_version: Version, ) -> Result<Vec<&'static CStr>, UnsupportedBackend>

pub fn required_layers( entry: &Entry, ) -> Result<Vec<&'static CStr>, UnsupportedBackend>

pub unsafe fn from_raw( entry: Entry, raw_instance: Instance, driver_api_version: Version, extensions: Vec<&'static CStr>, ) -> Result<Self, UnsupportedBackend>

Safety

raw_instance must be created using at least the extensions provided by Instance::required_extensions() and the layers provided by Instance::required_extensions(). driver_api_version must match the version used to create raw_instance. extensions must match the extensions used to create raw_instance. raw_instance must be manually destroyed after gfx-hal Instance has been dropped.

pub unsafe fn adapter_from_raw( &self, raw_physical_device: PhysicalDevice, ) -> Adapter<Backend>

Safety

raw_physical_device must be created from self (or from the inner raw handle)

Trait Implementations

impl Debug for Instance

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Instance<Backend> for Instance

fn create(name: &str, version: u32) -> Result<Self, UnsupportedBackend>

Create a new instance.

fn enumerate_adapters(&self) -> Vec<Adapter<Backend>>

Return all available graphics adapters.

unsafe fn create_surface( &self, has_handle: &impl HasRawWindowHandle, ) -> Result<Surface, InitError>

Create a new surface.

unsafe fn destroy_surface(&self, surface: Surface)

Destroy a surface, freeing the resources associated with it and releasing it from this graphics API.

unsafe fn create_display_plane_surface( &self, display_plane: &DisplayPlane<'_, Backend>, plane_stack_index: u32, transformation: SurfaceTransform, alpha: DisplayPlaneAlpha, image_extent: Extent2D, ) -> Result<Surface, DisplayPlaneSurfaceError>

Create a new surface from a display plane.
