Struct gdk4::VulkanContext

#[repr(transparent)]
pub struct VulkanContext { /* private fields */ }

VulkanContext is an object representing the platform-specific Vulkan draw context.

VulkanContexts are created for a surface using SurfaceExt::create_vulkan_context(), and the context will match the characteristics of the surface.

Support for VulkanContext is platform-specific and context creation can fail, returning None context.

This is an Abstract Base Class, you cannot instantiate it.

Signals

images-updated

Emitted when the images managed by this context have changed.

Usually this means that the swapchain had to be recreated, for example in response to a change of the surface size.

Implementations

impl VulkanContext

pub fn connect_images_updated<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

Emitted when the images managed by this context have changed.

Usually this means that the swapchain had to be recreated, for example in response to a change of the surface size.

Trait Implementations

impl Clone for VulkanContext

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VulkanContext

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

Formats the value using the given formatter.

impl Display for VulkanContext

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

Formats the value using the given formatter.

impl HasParamSpec for VulkanContext

type ParamSpec = ParamSpecObject

type SetValue = VulkanContext

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, VulkanContext>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for VulkanContext

fn hash<H>(&self, state: &mut H)where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for VulkanContext

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl ParentClassIs for VulkanContext

type Parent = DrawContext

impl<OT: ObjectType> PartialEq<OT> for VulkanContext

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for VulkanContext

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for VulkanContext

fn static_type() -> Type

Returns the type identifier of Self.
