Struct LocalFullChunkHolderCache 

pub(crate) struct LocalFullChunkHolderCache {
    scope_id: Option<NonZeroU64>,
    entries: [Option<LocalFullChunkHolderCacheEntry>; 4],
}

A tiny holder cache for repeated, live Full-chunk block-state reads.

Entries are usable only inside the exact gameplay lookup-cache scope that populated them. That scope is the proof that active-map membership is stable. The holder’s current Full permission and publication are rechecked for every read, and the block section itself is locked only long enough to copy the state. Missing and unpublished chunks are never retained.

Fields

scope_id: Option<NonZeroU64>

entries: [Option<LocalFullChunkHolderCacheEntry>; 4]

Implementations

impl LocalFullChunkHolderCache

pub(crate) const fn new() -> Self

pub(crate) fn block_state( &mut self, chunk_map: &ChunkMap, pos: BlockPos, ) -> Option<BlockStateId>

Reads the current state without retaining a section guard or a missing chunk result.

fn insert(&mut self, pos: ChunkPos, holder: Arc<ChunkHolder>)

fn promote(&mut self, index: usize)

fn remove(&mut self, index: usize)
