Struct RegionHeader 

pub struct RegionHeader {
    pub entries: Box<[ChunkEntry; 1024]>,
}

Region header containing chunk location table.

Fields

entries: Box<[ChunkEntry; 1024]>

Chunk entries (1024 = 32×32).

Implementations

impl RegionHeader

pub fn new() -> Self

Creates an empty header with no chunks.

pub const fn chunk_index(local_x: usize, local_z: usize) -> usize

Gets the local index for a chunk position within this region.

pub const fn index_to_local(index: usize) -> (usize, usize)

Converts a chunk index back to local coordinates.

pub fn to_bytes(&self) -> Vec<u8>

Serializes the header to bytes.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, usize>

Deserializes the header from bytes.

Panics

Panics if bytes length is not exactly CHUNK_TABLE_SIZE.

pub fn find_free_sectors(&self, sectors_needed: u32, file_sectors: u32) -> u32

Finds a contiguous range of free sectors for allocation.

Returns the starting sector offset, or None if no suitable range exists.

Trait Implementations

impl Default for RegionHeader

fn default() -> Self

Returns the “default value” for a type.
