Struct KernelGraphStore 

pub struct KernelGraphStore<B: MemoryBacking> { /* private fields */ }

Kernel-resident graph store.

Implements the graph_apply_proved syscall interface.

Implementations

impl<B: MemoryBacking> KernelGraphStore<B>

pub fn new( node_backing: B, edge_backing: B, witness_backing: B, node_handle: RegionHandle, edge_handle: RegionHandle, witness_handle: RegionHandle, capacity: u32, coherence_config: CoherenceConfig, proof_policy: ProofPolicy, partition_count: u32, store_id: u32, ) -> Result<Self>

Creates a new kernel graph store.

pub const fn handle(&self) -> GraphHandle

Returns the store handle.

pub fn node_count(&self) -> usize

Returns the number of nodes.

pub const fn edge_count(&self) -> u32

Returns the number of edges.

pub const fn capacity(&self) -> u32

Returns the capacity.

pub const fn partition_meta(&self) -> &PartitionMeta

Returns the partition metadata.

pub fn graph_apply_proved( &mut self, mutation: &GraphMutation, proof: &ProofToken, capability: &Capability, current_time_ns: u64, ) -> Result<GraphMutationResult>

Implements the graph_apply_proved syscall.

Applies a graph mutation with proof verification. Requires PROVE right on the capability.

Arguments

• mutation - The graph mutation to apply
• proof - The proof token authorizing the mutation
• capability - Capability authorizing the mutation
• current_time_ns - Current time for proof verification

Returns

A mutation result including the attestation.

pub const fn proof_policy(&self) -> &ProofPolicy

Returns the proof policy.

pub fn witness_entry_count(&self) -> usize

Returns witness log statistics.
