Struct ChunkHeightmaps 

pub struct ChunkHeightmaps {
    world_surface_wg: Option<Heightmap>,
    ocean_floor_wg: Option<Heightmap>,
    world_surface: Option<Heightmap>,
    motion_blocking: Option<Heightmap>,
    motion_blocking_no_leaves: Option<Heightmap>,
    ocean_floor: Option<Heightmap>,
}

Heightmap storage retained across every phase of a chunk.

Stores heightmaps as Option fields since they are lazily initialized based on the chunk’s generation status. Worldgen types (WorldSurfaceWg, OceanFloorWg) are used before CARVERS; final types are used after.

Fields

world_surface_wg: Option<Heightmap>

ocean_floor_wg: Option<Heightmap>

world_surface: Option<Heightmap>

motion_blocking: Option<Heightmap>

motion_blocking_no_leaves: Option<Heightmap>

ocean_floor: Option<Heightmap>

Implementations

impl ChunkHeightmaps

pub const fn empty() -> Self

Creates empty heightmap storage with no types initialized.

pub fn new(min_y: i32, height: i32) -> Self

Creates heightmap storage with every final chunk map initialized.

pub fn with_types(types: &[HeightmapType], min_y: i32, height: i32) -> Self

Creates storage with the requested heightmap types initialized at min_y.

pub const fn get(&self, heightmap_type: HeightmapType) -> Option<&Heightmap>

Returns a reference to a heightmap by type, if it exists.

pub const fn get_mut( &mut self, heightmap_type: HeightmapType, ) -> Option<&mut Heightmap>

Returns a mutable reference to a heightmap by type, if it exists.

pub fn replace(&mut self, heightmap: Heightmap)

Replaces one stored heightmap with a fully built instance.

fn get_or_insert( &mut self, heightmap_type: HeightmapType, min_y: i32, height: i32, ) -> &mut Heightmap

Returns a mutable reference to a heightmap, creating it if it doesn’t exist.

pub fn get_final(&self, heightmap_type: HeightmapType) -> &Heightmap

Returns a final heightmap required by a full chunk.

Panics

Panics if a worldgen type is requested or the final map is missing.

pub fn get_final_mut(&mut self, heightmap_type: HeightmapType) -> &mut Heightmap

Returns a mutable final heightmap required by a full chunk.

Panics

Panics if a worldgen type is requested or the final map is missing.

pub fn update_final<F>( &mut self, local_x: usize, y: i32, local_z: usize, state: BlockStateId, get_block: F, )

where F: Fn(usize, i32, usize) -> BlockStateId + Copy,

Updates every final heightmap after a full-chunk block change.

Panics

Panics if any required final heightmap is missing.

fn set_primed_height( &mut self, heightmap_type: HeightmapType, local_x: usize, local_z: usize, height: i32, )

pub fn prime_from_sections( &mut self, types: &[HeightmapType], min_y: i32, height: i32, sections: &[SectionHolder], )

Primes missing heightmaps by scanning each section under one read lock.
