Struct FluidStates 

pub struct FluidStates<'a> { /* private fields */ }

The fluid-state facts service, available in setup, reload and world callbacks after keys resolve.

Implementations

impl FluidStates<'_>

pub fn definition(&self, fluid: FluidKey) -> Option<FluidDefinition>

The definition, or none without a resolved registry. Missing prepared world definitions fail resource loading; they are never reported as tank-only.

pub fn type_properties(&self, fluid: FluidKey) -> Option<FluidTypeProperties>

The fluid’s type properties, or none without a resolved registry or for a key it doesn’t hold. Resolve a name with Host::fluid_key, which is none for an unknown one.

pub fn legacy_block(&self, state: FluidState) -> Option<BlockStateId>

FluidState.createLegacyBlock: the block state that holds state in the world, a water or lava block of the matching level, a mod’s world fluid’s block, or air for the empty fluid. None for a state no fluid can be in (a tank-only fluid, an amount above 8, a zero amount for anything but the empty fluid, a source that isn’t full) and without a resolved registry.

pub fn validate( &self, fluid: FluidKey, constraints: &[StateConstraint], ) -> Result<(), FluidStateError>

Validate partial constraints in input order, without matching a particular state. Tank-only or unavailable definitions return NoWorldState; use definition to distinguish them. Indices identify the first offending constraint.
