Struct FluidState 

pub struct FluidState {
    pub fluid_id: FluidRef,
    pub amount: u8,
    pub falling: bool,
}

A fluid state instance with amount and falling properties.

This is computed on-demand from block states rather than stored.

Fields

fluid_id: FluidRef

The fluid type (water, lava, empty).

amount: u8

The fluid amount (1-8, where 8 is a full block/source).

falling: bool

Whether the fluid is falling (flows downward faster).

Implementations

impl FluidState

pub const EMPTY: Self

The empty fluid state.

pub const fn new(fluid: FluidRef, amount: u8, falling: bool) -> Self

Creates a new fluid state.

pub const fn source(fluid: FluidRef) -> Self

Creates a source fluid state (amount=8, not falling).

pub const fn flowing(fluid: FluidRef, amount: u8, falling: bool) -> Self

Creates a flowing fluid state.

pub const fn is_empty(&self) -> bool

Returns true if this is the empty fluid.

pub const fn is_source(&self) -> bool

Returns true if this is a source block (full fluid, not falling).

Checks both the registry fluid_id.is_source flag (primary discriminator, equivalent to vanilla checking if the type is a SourceFluid) and the data invariant amount == 8 && !falling, guarding against malformed chunk data.

pub fn own_height(&self) -> f32

Returns the fluid’s own height (0.0 to ~0.89).

pub const fn from_block_level(fluid: FluidRef, level: u8) -> Self

Decodes a fluid state from a liquid block’s LEVEL property (0-15).

• LEVEL 0 = source (amount=8, falling=false)
• LEVEL 1-7 = flowing levels 7-1 (amount = 8 - level)
• LEVEL 8-15 = falling fluid (amount=8, falling=true, but clamped)

pub const fn to_block_level(self) -> u8

Encodes this fluid state to a liquid block’s LEVEL property (0-15).

Trait Implementations

impl Clone for FluidState

fn clone(&self) -> FluidState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FluidState

impl Debug for FluidState

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

Formats the value using the given formatter.

impl Eq for FluidState

impl FluidStateExt for FluidState

fn is_water(&self) -> bool

Returns true if this fluid state contains water.

fn is_lava(&self) -> bool

Returns true if this fluid state contains lava.

impl PartialEq for FluidState

fn eq(&self, other: &FluidState) -> 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.
