Struct PersistentBfsPlanCacheKey 

pub struct PersistentBfsPlanCacheKey {
    pub layout_hash: u64,
    pub node_count: u32,
    pub edge_count: u32,
    pub words_per_query: u32,
    pub query_count: u32,

    pub kind: PersistentBfsPlanCacheKind,
}

Primitive-owned persistent-BFS program cache key.

Dispatch wrappers add only backend feature bits; graph identity, frontier width, query count, masks, iteration budget, and plan class are owned here so every backend caches the same primitive program shapes.

Fields

layout_hash: u64

Stable discriminator for the cached program layout.

Content-addressed graph staging should use crate::graph::persistent_bfs::persistent_bfs_layout_hash. Program caches should prefer crate::graph::persistent_bfs::persistent_bfs_program_layout_hash so same-shape CSR contents reuse the same compiled persistent-BFS program.

node_count: u32

Number of graph nodes in the primitive program shape.

edge_count: u32

Number of logical graph edges in the primitive program shape.

words_per_query: u32

Number of frontier words per query.

query_count: u32

Number of queries represented by the program.

allow_mask: u32

Edge-kind allow mask compiled into the primitive program.

max_iters: u32

Iteration budget compiled into the primitive program.

device_features: u64

Backend/device feature key supplied by the dispatch wrapper.

kind: PersistentBfsPlanCacheKind

Single-query or batched-query plan kind.
