Interoperability

The interoperability subsystems cover three different memory workflows: WasmGPU's built-in Rust/WebAssembly driver memory, caller-managed frame and heap arenas inside that memory, and typed access to foreign WebAssembly modules or Python-owned array data.

In This Section

• Built-in driver memory views and shared-memory checks
• Frame arena scratch allocation and epoch-based lifetime rules
• Heap arena allocation with deterministic backing-block release
• External WebAssembly module memory access through WasmModule and WasmMemoryView
• Borrowed WasmMemoryView upload sources for geometry and scientific objects
• Python ndarray transfer helpers with guarded, idempotent heap-handle release
