Enum MemoryPoolLayout 

pub enum MemoryPoolLayout {
    Sliced(Vec<SlicedPool>),
    Direct,
    SubSlices,
    ExclusivePages,
}

A layout for a device’s dynamic memory pools, applied with Backend::memory_install_pools.

Variants

Sliced(Vec<SlicedPool>)

An ordered list of pools that sub-slice fixed-size pages. An allocation lands in the first pool whose max_slice accepts its size, so a small pool listed before a large one captures the small-allocation traffic. Pages are allocated on first use.

Direct

One direct pool for everything: every allocation is its own, sized to the request and reused by exact size — no pages, no sub-slicing, no padding beyond alignment. With no page size chosen in advance, this is what a workload runs on for its largest allocation to be read back as it was asked for.

SubSlices

The runtime’s default: a ladder of size-bucketed pools that sub-slice large pages.

ExclusivePages

One page per allocation, in exponentially spaced size buckets.
