Trait IPlatformGraphics 

pub trait IPlatformGraphics: Send + Sync {
    // Required methods
    fn uses_shared_context(&self) -> bool;
    fn create_context(&self) -> Rc<dyn IPlatformGraphicsContext>;
    fn get_shared_context(&self) -> Rc<dyn IPlatformGraphicsContext>;

    // Provided method
    fn as_feature_provider(&self) -> Option<&dyn IOptionalFeatureProvider> { ... }
}

Entry point to a platform GPU API (Metal, OpenGL, Vulkan, …).

The object is shared by threads, as in the reference, where the platform registers one object that the UI thread finds among its services and the thread that renders asks for its context. It is therefore held in an Arc and is Send + Sync: the platform creates it on its thread, the compositor hands a handle to the server side, and either side may clone, call and drop its handle without the other. An implementation holds only what two threads may share; what belongs to one thread (a display or a context that is an Rc) it keeps bound to that thread.

A context it creates is an object of the thread that asked for it.

Required Methods

fn uses_shared_context(&self) -> bool

Whether the backend renders through one context shared by all surfaces.

fn create_context(&self) -> Rc<dyn IPlatformGraphicsContext>

Creates a new graphics context.

fn get_shared_context(&self) -> Rc<dyn IPlatformGraphicsContext>

The shared graphics context; only valid when uses_shared_context is true.

Provided Methods

fn as_feature_provider(&self) -> Option<&dyn IOptionalFeatureProvider>

Optional features of the graphics API, if the implementation provides any.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
