Crate ustreamer_capture 

GPU frame capture from wgpu render targets.

Provides a trait FrameCapture with platform-specific implementations:

• Metal/IOSurface (macOS): zero-copy via wgpu-hal Metal interop
• Vulkan/CUDA (NVIDIA): zero-copy via external memory export
• Staging buffer (fallback): triple-buffered copy_texture_to_buffer

Modules

Structs

Diagnostic checksum over canonical RGBA8 pixel bytes.

Enums
