Struct SectionHolder 

pub struct SectionHolder {
    section: SyncRwLock<ChunkSection>,
    randomly_ticking_sections: Arc<RandomTickSectionBits>,
    section_index: usize,
}

A wrapper around a chunk section.

Fields

section: SyncRwLock<ChunkSection>

The chunk section data (requires lock to access).

randomly_ticking_sections: Arc<RandomTickSectionBits>

Shared lock-free random-tick section index.

section_index: usize

Implementations

impl SectionHolder

pub fn new(section: ChunkSection) -> Self

Creates a new section holder.

fn with_random_tick_index( section: ChunkSection, randomly_ticking_sections: Arc<RandomTickSectionBits>, section_index: usize, ) -> Self

pub fn is_randomly_ticking(&self) -> bool

Returns true if this section contains any randomly-ticking blocks or fluids.

The mirror may briefly be stale relative to a concurrent section writer. Section contents and the authoritative counter remain protected by the section lock.

pub fn read(&self) -> RwLockReadGuard<'_, ChunkSection>

Acquires a read lock on the section.

pub fn try_read(&self) -> Option<RwLockReadGuard<'_, ChunkSection>>

Attempts to acquire a read lock on the section.

pub fn write(&self) -> SectionWriteGuard<'_>

Acquires a write lock on the section.

pub fn try_write(&self) -> Option<SectionWriteGuard<'_>>

Attempts to acquire a write lock on the section.

Trait Implementations

impl Debug for SectionHolder

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

Formats the value using the given formatter.
