Struct ChunkLightData 

pub struct ChunkLightData {
    pub block: ChunkLightLayerStorage,
    pub sky: ChunkLightLayerStorage,
}

Chunk-owned block and sky light storage.

Fields

block: ChunkLightLayerStorage

Block light sections and section emptiness metadata.

sky: ChunkLightLayerStorage

Sky light sections and section emptiness metadata.

Implementations

impl ChunkLightData

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

Creates empty light storage for one chunk.

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

Creates storage for world heights already accepted by chunk construction.

Invalid world heights are fatal because chunk-owned light arrays cannot be indexed coherently without the vanilla padded light-section range.

Panics

Panics when the supplied world height cannot form a valid light-section range.

pub fn refresh_emptiness_maps_from_sections( &mut self, sections: &Sections, ) -> Result<(), ChunkLightEmptinessMapLengthError>

Refreshes both layer emptiness maps from current chunk section counters.

pub fn set_section_empty(&mut self, section_y: i32, empty: bool) -> bool

Updates one real chunk section’s known emptiness in both light layers.

pub fn get_light_value(&self, layer: LightLayer, block_pos: BlockPos) -> u8

Returns the visible light value for one layer at a block position.

Trait Implementations

impl Debug for ChunkLightData

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

Formats the value using the given formatter.
