}

Physical allocation accounting for the entire default memory runtime.

The ledger is already included in totals. Virtual extent is addressable memory, not live payload. Unknown bindings still own physical allocations.

Fields

current_generation: Option<u64>

Committed runtime generation, absent before allocation bootstrap.

manager_layout_version: u8

Validated manager layout version.

bucket_size_pages: u16

Actual persisted bucket size in Wasm pages.

bucket_size_bytes: u64

Actual persisted bucket size in bytes.

bucket_capacity: u32

Total bucket-table capacity shared by all slots.

allocated_buckets: u16

Number of assigned buckets.

remaining_buckets: u32

Remaining bucket-table entries.

maximum_bucket_bytes: u64

Table capacity in bytes, excluding metadata and backing limits.

physical_extent: MemoryExtent

Entire backing extent, including manager metadata and residuals.

virtual_extent: MemoryExtent

Sum of addressable virtual extents.

manager_metadata_bytes: u64

Complete manager metadata page, including padding.

manager_header_bytes: u64

Manager header bytes.

manager_bucket_table_bytes: u64

Manager bucket-table bytes.

manager_padding_bytes: u64

Padding inside the manager metadata page.

allocated_bucket_bytes: u64

Sum of bytes assigned to all slots, including the ledger.

bucket_slack_bytes: u64

Assigned bucket bytes beyond virtual extents.

known_binding_bytes: u64

Assigned bytes with a current binding, including the ledger.

unknown_binding_bytes: u64

Assigned bytes without a current binding; not free space.

unmanaged_bytes: u64

Backing bytes outside the manager’s assigned region.

metadata_bytes_read: u64

Metadata bytes read by the bounded collector.

memories: Vec<MemoryAllocation>

All 255 usable slots in ID order, including zero-size slots.
