Enum AllocationPolicy 

pub enum AllocationPolicy {
    Separate,
    Automatic,
    Pooled {
        block_size: u64,
    },
    Adaptive {
        block_size: u64,
        min_block_size: u64,
    },
}

Managed resource storage policy. Required or preferred native dedication takes precedence.

Variants

Separate

Automatic

Heap-sized default pools with pinned VMA growth, reuse and separate fallback.

Pooled

Reuse ordinary buffer blocks with this exact native size. No block shrinking. Requests larger than the block use separate storage.

Fields

block_size: u64

Adaptive

Try bounded power-of-two block sizes, shrinking only on recoverable storage failure. Large regions and exhausted block attempts fall back to separate storage.

Fields

block_size: u64

min_block_size: u64
