Struct StructureData 

pub struct StructureData {
    pub key: Identifier,
    pub id: OnceLock<usize>,
    pub structure_type: Identifier,
    pub allowed_biomes: Vec<Identifier>,
    pub spawn_overrides: Vec<StructureSpawnOverrideData>,
    pub step: StructureGenerationStep,
    pub terrain_adjustment: TerrainAdjustment,
    pub config: StructureConfigData,
}

A registered worldgen structure definition.

Mirrors vanilla’s Structure: common settings are stored here, while StructureConfigData carries the type-specific codec payload.

Fields

key: Identifier

Registry key, e.g. minecraft:village_plains.

id: OnceLock<usize>

Cached registry ID, set during registration for O(1) lookup on hot paths.

structure_type: Identifier

Structure type, e.g. minecraft:jigsaw or minecraft:mineshaft.

allowed_biomes: Vec<Identifier>

Biomes this structure can generate in. Tags are resolved at build time.

spawn_overrides: Vec<StructureSpawnOverrideData>

Structure-specific mob spawn overrides.

step: StructureGenerationStep

Generation decoration step from the structure JSON.

terrain_adjustment: TerrainAdjustment

Terrain adaptation used by reference inflation and Beardifier.

config: StructureConfigData

Type-specific structure config.

Implementations

impl StructureData

pub const fn bb_inflate(&self) -> i32

Vanilla inflates the structure start bounding box by 12 for every terrain adaptation mode except none.

Trait Implementations

impl Debug for StructureData

Formats the value using the given formatter.

impl RegistryEntry for StructureData
