EXTMemoryBudget (LWJGL 3.2.3 SNAPSHOT)

java.lang.Object
- org.lwjgl.vulkan.EXTMemoryBudget

```
public final class EXTMemoryBudget
extends java.lang.Object
```
This extension adds support for querying the amount of memory used and the total memory budget for a memory heap. The values returned by this query are implementation-dependent and can depend on a variety of factors including operating system and system load.
The heapBudget values can be used as a guideline for how much total memory from each heap the process can use at any given time, before allocations may start failing or causing performance degradation. The values may change based on other activity in the system that is outside the scope and control of the Vulkan implementation.
