Struct GpuFileFooter 

pub struct GpuFileFooter {
    pub index_offset: u64,
    pub index_size: u32,
    pub footer_checksum: u32,
    pub format_version: u32,
    pub magic: [u8; 4],
}

Fixed 24-byte record at the very end of every GPU archive.

Fields

index_offset: u64

Absolute byte offset of the TileIndexHeader from start of file.

index_size: u32

Byte length of the index region.

footer_checksum: u32

CRC32 of bytes [0..12] of this footer.

format_version: u32

Redundant copy of format version.

magic: [u8; 4]

Implementations

impl GpuFileFooter

pub const SIZE: usize = 24

pub fn new(index_offset: u64, index_size: u32) -> Self

Build and compute the footer checksum.

pub fn to_bytes(self) -> [u8; 24]

Serialize to 24 bytes.

pub fn from_bytes(b: &[u8; 24]) -> Result<Self>

Deserialize and validate a 24-byte footer.

Errors

• CrushError::InvalidFormat if magic is wrong or checksum fails.
• CrushError::VersionMismatch if format version differs.

Trait Implementations

impl Clone for GpuFileFooter

fn clone(&self) -> GpuFileFooter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuFileFooter

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

Formats the value using the given formatter.

impl PartialEq for GpuFileFooter

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