TopologyRestoreInput

laminar_core::cluster::control::topology

Struct TopologyRestoreInput 

Source 
pub struct TopologyRestoreInput { /* private fields */ }
Expand description

A live read of the exact prepared operation, cut and local ownership. Only the configured controller/authority can construct this input. It permits private restore preparation, never graph installation, source start, output or intake release. A retained input can become stale; installation must revalidate authority and require a target Commit/Release.

Implementations§

Source§

impl TopologyRestoreInput

Source

pub fn processes(&self) -> &[LocalProcessAuthorityIdentity]

Exact current owner/evidence roster revalidated for committed reconstruction.

Source

pub fn current_leader(&self) -> Option<LeaderProof>

Current committed reconstruction leader, absent for pre-Commit private preparation.

Source

pub fn same_restore_requirements(&self, other: &Self) -> bool

Compare all restore requirements, allowing only monotonic receipt/status progress. Both inputs must come from current controller authorization; this comparison never replaces a fresh read or the authority’s receipt, leader, process and assignment audits.

Source

pub fn same_installed_generation(&self, other: &Self) -> bool

Immutable installed generation, excluding the current leader read. A leader change after Commit never changes the restored state; current installation/Release must be audited anew.

Source

pub fn is_committed_successor_of(&self, prepared: &Self) -> bool

Whether a fresh committed authorization retains the prepared image’s exact historical requirements and local process. This compares images only, never grants output or Release.

Source

pub const fn assignment(&self) -> &CheckpointAssignmentFence

Exact current assignment authorizing this private reconstruction. Historical state and source attempts retain plan().assignment; recovery may replace boots with the same owners.

Source

pub const fn is_committed(&self) -> bool

Whether this is explicit committed-root reconstruction, still without installation/Release.

Source

pub const fn operation(&self) -> &TopologyAdmissionStatus

Exact prepared or committed operation, including its root authority anchor.

Source

pub const fn plan(&self) -> &TopologyAdmissionPlan

Immutable admitted plan and assignment.

Source

pub const fn parent(&self) -> &CatalogManifest

Complete exact predecessor inventory. Removals cannot be inferred from a target prefix.

Source

pub const fn target(&self) -> &CatalogManifest

Complete sealed target inventory, committed only when this authorization records Commit.

Source

pub const fn descriptor(&self) -> &ClusterTopologyValidation

Independently certified parent/target and per-object contracts.

Source

pub const fn root(&self) -> &TopologyMigrationRoot

Immutable requirements, including sealed source positions and subscription mappings.

Source

pub const fn outcome(&self) -> &CheckpointOutcome

Definitive old-topology checkpoint Commit; never a target Commit.

Source

pub const fn checkpoint(&self) -> &CommittedCheckpointIndex

Exact historical index, retaining the parent pipeline identity.

Source

pub fn owned_vnodes(&self) -> &[u32]

Canonical local vnode roster from the unchanged current assignment.

Source

pub const fn process(&self) -> LocalProcessAuthorityIdentity

Exact process incarnation and term for this preparation.
