Struct DiskRowWarmCache

Source

pub struct DiskRowWarmCache { /* private fields */ }

Expand description

mmap/LRU-backed disk cache implementing RowWarmCache.

Bound to one TermCollectionSpec structural hash at construction; every key folds that hash so two topologies cannot collide.

Implementations§

Source §

impl DiskRowWarmCache

Source

pub fn new(spec: &TermCollectionSpec) -> Self

Construct a cache bound to spec’s structural topology, deriving the per-topology structural hash the same way the existing warm-start cache does (#869) — via write_structural_shape_hash.

Trait Implementations§

Source §

impl RowWarmCache for DiskRowWarmCache

Source §

fn get(&mut self, row_id: u64) -> Option<RowWarmState>

Fetch the warm state for row_id under this cache’s bound topology, if present (in-process LRU first, then disk).

Source §

fn put(&mut self, row_id: u64, state: &RowWarmState)

Store / overwrite the warm state for row_id.
