MemoryAllocationSummary

Bounded numeric allocation accounting without per-ID rows, stable keys, owners or pool metadata. Uses the same validated metadata and conservation equations as MemoryAllocations. Binding groups describe current runtime provenance; unknown includes omitted or retired keys without reading history. No payload occupancy is available.

Fields

current_generation: Option<u64>

In-memory committed generation; unavailable before bootstrap.

bucket_size_pages: u16

Actual persisted bucket size, never a requested/default assumption.

allocated_buckets: u16

physical_extent: DiagnosticMemorySize

virtual_extent: DiagnosticMemorySize

current_binding: MemoryBindingSummary

ledger_binding: MemoryBindingSummary

unknown_binding: MemoryBindingSummary

Implementations

impl MemoryAllocationSummary

pub const MANAGER_LAYOUT_VERSION: u8 = 1

Supported, validated manager layout identity.

pub const BUCKET_CAPACITY: u32

Finite table capacity, excluding metadata and backing limits.

pub const MANAGER_METADATA_BYTES: u64 = WASM_PAGE_SIZE_BYTES

The complete metadata page, including header, table and padding.

pub const MANAGER_HEADER_BYTES: u64

Fixed manager header bytes.

pub const MANAGER_BUCKET_TABLE_BYTES: u64

Fixed bucket ownership table bytes.

pub const MANAGER_PADDING_BYTES: u64

Remaining metadata-page bytes.

pub const METADATA_BYTES_READ: u64

Exact metadata read budget, independent of ledger history and payload.

pub const MEMORIES_MEASURED: u16

Number of usable IDs, including empty IDs and governance.

pub const fn bucket_size_bytes(&self) -> u64

Bytes in each measured bucket.

pub const fn remaining_buckets(&self) -> u32

Available bucket ownership entries, not backing-memory availability.

pub const fn maximum_bucket_bytes(&self) -> u64

Maximum assigned bucket capacity, excluding metadata.

pub const fn allocated_bucket_bytes(&self) -> u64

Assigned bucket capacity across all IDs.

pub const fn bucket_slack_bytes(&self) -> u64

Assigned capacity beyond all virtual extents.

pub const fn known_binding_bytes(&self) -> u64

Assigned bytes belonging to current declarations or governance.

pub const fn unknown_binding_bytes(&self) -> u64

Assigned bytes with no current declaration binding.

pub const fn unmanaged_bytes(&self) -> u64

Backing bytes after metadata and the assigned bucket region.
