Struct TileHeader 

pub struct TileHeader {
    pub version: u8,
    pub flags: TileFlags,
    pub sub_stream_count: u8,
    pub compressed_size: u32,
    pub uncompressed_size: u32,
    pub checksum: u32,
    pub sub_stream_offsets_size: u32,
}

Fixed 32-byte header preceding each compressed tile’s payload.

Fields

version: u8

Tile format version (initially 1). Decompressor rejects unknown versions.

flags: TileFlags

sub_stream_count: u8

compressed_size: u32

uncompressed_size: u32

checksum: u32

CRC32 of the uncompressed tile data. 0 if checksums disabled.

sub_stream_offsets_size: u32

Size of the sub-stream offset table in bytes.

Implementations

impl TileHeader

pub const SIZE: usize = 32

pub fn to_bytes(self) -> [u8; 32]

Serialize to 32 bytes (little-endian).

pub fn from_bytes(b: &[u8; 32]) -> Self

Deserialize from 32 bytes.

Trait Implementations

impl Clone for TileHeader

fn clone(&self) -> TileHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TileHeader

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

Formats the value using the given formatter.

impl PartialEq for TileHeader

fn eq(&self, other: &TileHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
