Module memory 

Common native shared-memory allocation, policy, and cleanup interface. Common lifecycle and policy interface for the best native shared-memory backend.

The region-to-prepared-to-batch path composed by crate::region, crate::batch, and crate::session is the supported transfer route; crate::memory::NativeRegion::prepare_for_sharing exists for the documented lower-level boundary directly on this module’s own types and has no public transfer consumer.

Structs

NativeMemoryCapabilities

Cross-platform capabilities of the selected native backend.

NativeRegion

Common owner of the best private native shared-memory object on this target.

NativeShareRequest

Consuming boundary between common memory management and native transfer.

PermissionPlan

Exact creator/peer access requested for the future sharing transition.

RegionOptions

Immutable configuration for one native shared-memory region.

RegionStatus

Snapshot of a managed region’s portable state and policy.

Enums

AuthorityMechanism

Kernel mechanism that freezes shared-memory authority before transfer.

CleanupPolicy

Cleanup policy applied while the common wrapper still owns the region.

GrowthPolicy

Capacity policy while a region is still private and quiescent.

MemoryAccess

Planned access for one endpoint after the sharing transition.

MemoryError

Portable allocation, policy, or lifecycle failure.

NativeArchitecture

Processor architecture selected for the native backend.

NativePlatform

Native backend selected for the compilation target.

RegionState

Current common lifecycle state.

SealPolicy

Mandatory authority-sealing policy for shared regions.

WriterOwner

Endpoint that will retain the sole writable mapping after transfer.

Functions

native_memory_capabilities

Reports the native memory behavior selected for this target.
