pub struct Snapshot { /* fields omitted */ }

A snapshot of the state of the world.

Implementations

impl Snapshot

pub fn empty(universe: Arc<Universe>) -> Snapshot

Create a new snapshot of an empty world.

pub fn universe(&self) -> &Arc<Universe>

Get a weak reference to the owning universe of this snapshot.

pub fn chunk_sets(&self) -> &[ChunkSet]

Get all the ChunkSets in this snapshot.

pub fn par_iter_chunk_sets(&self) -> impl ParallelIterator<Item = &ChunkSet>

Create a parallel iterator over the chunks in the snapshot.

pub fn iter_chunk_sets(&self) -> impl Iterator<Item = &ChunkSet>

Create an iterator over all chunk sets.

pub fn par_iter_chunks(&self) -> impl ParallelIterator<Item = &Arc<Chunk>>

Create a parallel iterator over the chunks in the snapshot.

pub fn iter_chunks(&self) -> impl Iterator<Item = &Arc<Chunk>>

Create an iterator over all the chunks in the snapshot.

pub fn chunk_set(&self, a: &Arc<Archetype>) -> Option<&ChunkSet>

Get the ChunkSet for a particular archetype.

pub fn entity(&self, id: EntityID) -> Option<EntityEntry>

Get an EntityEntry for the entity with the given ID.

Returns None if the entity doesn’t exist in this snapshot.

pub fn modify<'a, E>(self: &mut Arc<Self>, edits: E) where
    E: Iterator<Item = Edit<'a>>, 

Modify this snapshot, producing another snapshot, with the given edit list applied.

If this is the only Arc to this snapshot, the memory will be reused. This is also true of the contained ChunkSets and Chunks.
