Struct GpuFileHeader 

pub struct GpuFileHeader {
    pub magic: [u8; 4],
    pub format_version: u32,
    pub engine_version: EngineVersion,
    pub tile_size: u32,
    pub sub_stream_count: u8,
    pub flags: GpuFileFlags,
    pub uncompressed_size: u64,
    pub tile_count: u64,
}

Fixed 64-byte header at the start of every GPU-compressed archive.

Fields

magic: [u8; 4]

format_version: u32

engine_version: EngineVersion

tile_size: u32

sub_stream_count: u8

flags: GpuFileFlags

uncompressed_size: u64

tile_count: u64

Implementations

impl GpuFileHeader

pub const SIZE: usize = 64

pub fn new(tile_count: u64, uncompressed_size: u64) -> Self

Build a header with default tile size (64KB) and sub-stream count (32).

pub fn to_bytes(&self) -> [u8; 64]

Serialize to exactly 64 bytes (little-endian).

pub fn from_bytes(b: &[u8; 64]) -> Result<Self>

Deserialize and validate a 64-byte slice.

Errors

• CrushError::InvalidFormat if magic bytes are wrong.
• CrushError::VersionMismatch if format_version differs.

Trait Implementations

impl Clone for GpuFileHeader

fn clone(&self) -> GpuFileHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuFileHeader

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

Formats the value using the given formatter.

impl PartialEq for GpuFileHeader

fn eq(&self, other: &GpuFileHeader) -> 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.
