MemoryPressureInjector class

Simulates memory pressure to test how an AI model behaves near or beyond its available RAM budget.

The injector delegates memory allocation to the AIModelAdapter via AIModelAdapter.simulateMemoryPressure, allowing adapters that wrap real native models to trigger actual OS-level memory pressure if desired.

Usage

final injector = MemoryPressureInjector(
  model:   myAdapter,
  limitMb: 150,
);

await injector.inject();   // allocates 150 MB
// … run inference …
await injector.reset();    // releases memory
