Struct LightPropagationQueue 

pub struct LightPropagationQueue {
    entries: Vec<QueuedLightUpdate>,
    read_index: usize,
}

Array-backed FIFO used for vanilla light propagation work.

Vanilla stores alternating packed block positions and QueueEntry longs in LongArrayFIFOQueue. Steel keeps typed records instead, while preserving the FIFO ordering and packed queue-entry semantics that propagation depends on.

Fields

entries: Vec<QueuedLightUpdate>

read_index: usize

Implementations

impl LightPropagationQueue

pub fn new() -> Self

Creates an empty propagation queue.

pub const fn is_empty(&self) -> bool

Returns true when no queued work remains.

pub const fn len(&self) -> usize

Returns the number of queued items that have not been dequeued yet.

pub fn enqueue(&mut self, block_pos: BlockPos, entry: LightQueueEntry)

Adds propagation work to the back of the queue.

pub fn dequeue(&mut self) -> Option<QueuedLightUpdate>

Removes propagation work from the front of the queue.

pub fn clear(&mut self)

Removes all queued work while keeping allocated storage for reuse.

Trait Implementations

impl Debug for LightPropagationQueue

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

impl Default for LightPropagationQueue

fn default() -> Self

Returns the “default value” for a type.
