Skip to main content Crate frame_alloc Copy item path Source DefaultGates Default, production gate values. DepotAllocator A per-CPU magazine cache with a shared depot tier, over a backing physical
allocator. This extends MagazineAllocator NoCpuId Default implementation: routes everything to index 0. NoInterruptControl The default InterruptControlnot safe to call from an interrupt handler . PageSize A power-of-two page size, stored as a bit-shift (log2 of bytes). PhysRange A physically-contiguous, base-frame-aligned range of usable RAM. RegionedAllocator A wrapper that routes over REGIONS disjoint physical spansA per span. SummaryBuddyAllocator A lock-free, bitmap-only buddy allocator with a two-level summary bitmap
that carves its bitmap out of the managed physical memory region at init time. AllocError InitError Structured failure reason for RegionInit::try_init CpuId Strategy for mapping the calling CPU to a slot index. GateConfig Compile-time tuning of the two summary-scan gates. InterruptControl Strategy for disabling and restoring local (per-CPU) interrupts . PhysicalAllocator Trait for physical frame allocators. Provenance Strategy for obtaining and relinquishing compiler provenance on physical
frame pointers. RegionInit Memory-map-aware initialisation interface for physical frame allocators.
