Struct SemanticIndexCache 

pub struct SemanticIndexCache { /* private fields */ }

Per-slice index cache keyed by (dim_range.start, dim_range.end).

Implementations

impl SemanticIndexCache

pub fn new() -> Self

Create an empty cache at epoch 0.

pub fn bump(&self)

Record a mutation that may change semantic query results. Callers must apply the mutation before bumping.

pub fn epoch(&self) -> u64

Current epoch (test/diagnostic visibility).

pub fn get_or_build<F>( &self, dim_range: &Range<usize>, snapshot: F, ) -> Arc<SliceIndex>

where F: FnOnce() -> Vec<(String, Vec<FixedPoint>)>,

Get the cached tree for dim_range, or build one via snapshot (a coherent read of all nodes’ decoded slice coordinates) and cache it.

snapshot runs without any cache lock held, so concurrent queries on other slices are never blocked by a build.

pub fn cached_slice_count(&self) -> usize

Number of currently cached slices (test visibility).

Trait Implementations

impl Default for SemanticIndexCache

fn default() -> Self

Returns the “default value” for a type.
