Struct ChunkEntry 

pub struct ChunkEntry {
    pub sector_offset: u32,
    pub size_bytes: u32,
    pub status: ChunkStatus,
}

Entry in the chunk location table.

Layout (8 bytes total):

• offset: u32 - sector offset (0 = chunk doesn’t exist)
• size: u24 - compressed size in bytes
• flags: u8 - status and flags

Fields

sector_offset: u32

Sector offset from start of file. 0 means chunk doesn’t exist. Multiply by SECTOR_SIZE to get byte offset.

size_bytes: u32

Size of compressed chunk data in bytes (stored as u24, max ~16MB).

status: ChunkStatus

Chunk status (generation state).

Implementations

impl ChunkEntry

pub const fn new( sector_offset: u32, size_bytes: u32, status: ChunkStatus, ) -> Self

Creates a new chunk entry.

pub const fn exists(&self) -> bool

Returns true if this entry represents an existing chunk.

pub const fn empty() -> Self

Creates an empty/non-existent chunk entry.

pub const fn sector_count(&self) -> u32

Calculates the number of sectors this chunk occupies.

pub const fn to_bytes(self) -> [u8; 8]

Serializes to 8 bytes: [offset: 4][size: 3][flags: 1]

pub fn from_bytes(bytes: [u8; 8]) -> Option<Self>

Deserializes from 8 bytes.
