Struct re_query::range::RangeCache

source · 
pub struct RangeCache {
    pub cache_key: QueryCacheKey,
    pub chunks: HashMap<ChunkId, RangeCachedChunk>,
    pub pending_invalidations: BTreeSet<ChunkId>,
}
Expand description

Caches the results of Range queries for a given QueryCacheKey.

Fields§

§cache_key: QueryCacheKey

For debugging purposes.

§chunks: HashMap<ChunkId, RangeCachedChunk>

All the [Chunk]s currently cached.

See RangeCachedChunk for more information.

§pending_invalidations: BTreeSet<ChunkId>

Every [ChunkId] present in this set has been asynchronously invalidated.

The next time this cache gets queried, it must remove any entry matching any of these IDs.

Invalidation is deferred to query time because it is far more efficient that way: the frame time effectively behaves as a natural micro-batching mechanism.

Implementations§

source§

impl RangeCache

source

pub fn new(cache_key: QueryCacheKey) -> Self

source

pub fn time_range(&self) -> ResolvedTimeRange

Returns the time range covered by this RangeCache.

This is extremely slow (O(n)), don’t use this for anything but debugging.

source§

impl RangeCache

source

pub fn range( &mut self, store: &ChunkStore, query: &RangeQuery, entity_path: &EntityPath, component_name: ComponentName ) -> Vec<Chunk>

Queries cached range data for a single component.

source

pub fn handle_pending_invalidation(&mut self)
