Struct BufferHeapStats 

pub struct BufferHeapStats {
    pub buffer_count: u32,
    pub overflow_count: usize,
    pub high_water_bytes: u64,
    pub primary_heap_bytes: u64,
}

Snapshot of a Metal buffer heap allocator’s state.

Fields

buffer_count: u32

Total number of buffers ever allocated from the heap hierarchy (monotonically increasing). This counter does NOT decrease when buffers are freed.

overflow_count: usize

Number of overflow heaps currently alive (0 in steady state).

high_water_bytes: u64

Peak total bytes used across all heaps since last reset.

primary_heap_bytes: u64

Size of the primary heap in bytes.
