Implementations

impl HierarchyCache

pub fn new() -> Self

Create an empty hierarchy cache.

pub async fn load_root( &mut self, source: &impl ByteSource, info: &CopcInfo, ) -> Result<(), CopcError>

Load the root hierarchy page.

pub async fn load_pending_pages( &mut self, source: &impl ByteSource, ) -> Result<(), CopcError>

pub async fn load_all( &mut self, source: &impl ByteSource, info: &CopcInfo, ) -> Result<(), CopcError>

Load all pending pages (breadth-first).

pub fn has_pending_pages(&self) -> bool

Whether there are unloaded hierarchy pages.

pub fn get(&self, key: &VoxelKey) -> Option<&HierarchyEntry>
