Struct DiskLayerExportPlan 

pub struct DiskLayerExportPlan { /* private fields */ }

A contiguous suffix of an immutable checkpoint chain to include in an archive.

Unlike a runtime chain, every checkpoint layer is sealed. Its newest layer must not be subtracted as though it were the live writable head. Omitted layers are explicit dependencies.

Implementations

impl DiskLayerExportPlan

pub fn complete(checkpoint_layers: usize) -> Result<Self, LayerSelectionError>

Include every physical layer, with no external disk-layer dependencies.

pub fn last( checkpoint_layers: usize, layers: usize, ) -> Result<Self, LayerSelectionError>

Include the newest layers immutable layers; explicitly require the preceding prefix.

pub fn since<T: PartialEq>( target: &[T], baseline: &[T], ) -> Result<Self, LayerSelectionError>

Require an exact baseline prefix and include only later physical layers.

Supply comparable identity records containing both layer identity and interpretation metadata, not just filenames or logical parent IDs. Resolve archive-local backing paths before comparison. A compacted representation is not interchangeable with its old prefix.

pub fn included(&self) -> Range<usize>

Immutable payload layers to include, in oldest-first order.

pub fn required(&self) -> Range<usize>

Exact omitted prefix that the importer must resolve before publication or restore.

pub fn is_disk_complete(&self) -> bool

Whether the disk payload can be opened without an externally supplied prefix.
