Struct MemoryPoolReport 

pub struct MemoryPoolReport {
    pub kind: MemoryPoolKind,
    pub usage: MemoryUsage,
    pub pages: u64,
    pub pages_peak: u64,
    pub pages_unmapped: u64,
    pub largest_alloc: u64,
}

A structured snapshot of one memory pool: its shape, its current usage, and the high-water marks a memory plan is derived from.

Fields

kind: MemoryPoolKind

The pool’s shape and effective configuration.

usage: MemoryUsage

The pool’s current usage.

pages: u64

Device allocations (pages) currently held.

pages_peak: u64

The most device allocations ever held at once.

For a sliced pool this is the number a capped layout needs: pages are carved by a deterministic first-fit policy, so replaying the same allocation stream against pages_peak * page_size fits by construction.

pages_unmapped: u64

How many of the current pages have no device backing yet — carved under a dry run and never resolved into anything that executes. They count toward pages/pages_peak (the plan is the reserved stream) while costing no device memory; pages - pages_unmapped is the dry run’s actual footprint in this pool.

largest_alloc: u64

The largest single allocation this pool ever served, in requested (pre-padding) bytes.
