Fields

data_version: i32

Version of the chunk NBT structure.

x_pos: i32

x position of the chunk (in absolute chunks from world x, z origin, not relative to the region).

z_pos: i32

z position of the chunk (in absolute chunks from world x, z origin, not relative to the region).

y_pos: i32

Lowest Y section in chunk

status: NamespacedKey

Defines the world generation status of this chunk

All status except [Status::Full] are used for chunks called proto-chunks, in other words, for chunks with incomplete generation.

last_update: i64

Tick when the chunk was last saved.

block_entities: Vec<Value>

List of block entities in this chunk

height_maps: HeightMaps

Several different heightmaps corresponding to 256 values compacted at 9 bits per value (lowest being 0, highest being 384, both values inclusive).

fluid_ticks: Vec<Value>

List of “active” liquids in this chunk waiting to be updated

block_ticks: Vec<Value>

List of “active” blocks in this chunk waiting to be updated. These are used to save the state of redstone machines or falling sand, and other activity

inhabited_time: i64

The cumulative number of ticks players have been in this chunk. Note that this value increases faster when more players are in the chunk. Used for Regional Difficulty.

blending_data: Option<BlendingData>

This appears to be biome blending data, although more testing is needed to confirm.

post_processing: [Vec<Value>; 24]

A List of 24 Lists that store the positions of blocks that need to receive an update when a proto-chunk turns into a full chunk, packed in Shorts. Each list corresponds to specific section in the height of the chunk

structures: Value

Structure data in this chunk

sections: Vec<ChunkSection>

A list of the sections in this chunk

All sections in the world’s height are present in this list, even those who are empty (filled with air).

Trait Implementations

impl Clone for ChunkNbt

fn clone(&self) -> ChunkNbt

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChunkNbt

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChunkNbt

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ChunkNbt

fn eq(&self, other: &ChunkNbt) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
