Expand description

A trait to group common context operations.

Required Associated Types§

Source

type NotCurrentContext: NotCurrentGlContext

The not current context type.

Source

type Surface<T: SurfaceTypeTrait>: GlSurface<T>

The surface supported by the context.

Required Methods§

Source

fn is_current(&self) -> bool

Returns true if this context is the current one in this thread.

Source

fn make_not_current(self) -> Result<Self::NotCurrentContext>

Make the context not current to the current thread and returns a Self::NotCurrentContext to indicate that the context is a not current to allow sending it to the different thread.

§Platform specific
  • macOS: this will block if your main thread is blocked.
Source

fn make_not_current_in_place(&self) -> Result<()>

Make the context not current to the current thread. If you need to send the context to another thread, use Self::make_not_current instead.

Source

fn make_current<T: SurfaceTypeTrait>( &self, surface: &Self::Surface<T>, ) -> Result<()>

Make Self::Surface current on the calling thread.

§Platform specific
  • macOS: this will block if your main thread is blocked.
Source

fn make_current_draw_read<T: SurfaceTypeTrait>( &self, surface_draw: &Self::Surface<T>, surface_read: &Self::Surface<T>, ) -> Result<()>

The same as Self::make_current but provides a way to set read and draw surfaces explicitly.

§Api-specific:
  • CGL/WGL: not supported.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
