Struct PackedLightQueueEntry 

pub struct PackedLightQueueEntry(u64);

ScalableLux packed light-propagation queue entry.

The lower 28 bits store PackedLightBlockPos, followed by a 4-bit light level and a 6-bit LightDirectionSet. Bits 61, 62, and 63 carry LightQueueFlags; the middle 23 bits are intentionally unused to preserve ScalableLux’s layout.

Implementations

impl PackedLightQueueEntry

pub const fn from_parts( block_pos: PackedLightBlockPos, level: u8, directions: LightDirectionSet, flags: LightQueueFlags, ) -> Self

Creates a packed queue entry from typed ScalableLux parts.

pub const fn from_raw(raw: u64) -> Self

Creates a packed queue entry from raw ScalableLux queue bits.

pub const fn raw(self) -> u64

Returns the raw ScalableLux queue entry.

pub const fn block_pos(self) -> PackedLightBlockPos

Returns the packed block position stored in this queue entry.

pub const fn level(self) -> u8

Returns the propagated light level.

pub const fn directions(self) -> LightDirectionSet

Returns the propagation direction set.

pub const fn flags(self) -> LightQueueFlags

Returns the top-bit state flags.

pub const fn should_write_level(self) -> bool

Returns true when the increase pass should write this entry’s level.

pub const fn should_recheck_level(self) -> bool

Returns true when the increase pass should confirm the current level.

pub const fn has_sided_transparent_blocks(self) -> bool

Returns true when propagation must account for sided transparent shapes.
