Platform adapter that performs native GL or WebGL operations.

Implementations must not retain borrowed CPU memory after a call returns. The portable layer invokes these methods only after checking context identity, execution owner, current state, context loss, API identity, and policy.

Required Methods

fn api(&self) -> GraphicsApi

fn context_identity(&self) -> ContextIdentity

fn execution_owner(&self) -> ExecutionOwner

fn is_current(&self) -> bool

fn is_context_lost(&self) -> bool

fn capability( &self, source: FrameSource<'_>, destination: &FrameDestination<'_>, ) -> TransferMode

fn upload( &mut self, source: CpuFrameSource<'_>, destination: GraphicsResource, stages: &[TransferStage], ) -> Result<()>

fn readback( &mut self, source: GraphicsResource, destination: CpuFrameDestination<'_>, stages: &[TransferStage], ) -> Result<()>

fn copy( &mut self, source: GraphicsResource, destination: GraphicsResource, stages: &[TransferStage], ) -> Result<()>

fn delete(&mut self, resource: GraphicsResource) -> Result<()>

Dyn Compatibility

This trait is dyn compatible.

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