Struct FileHeaderV2 

pub struct FileHeaderV2 {
    pub patch_type: [u8; 4],
    pub entry_files: u32,
}

FHDR v2 body: minimal patch metadata from older patch files.

Version 2 headers appear in early FFXIV patch files. They carry only the patch type tag and an entry-file count; the extended statistics present in v3 are absent.

After the two fields listed here, the wire format includes 8 trailing zero bytes that the parser intentionally ignores.

See lib/FFXIVQuickLauncher/.../Chunk/FileHeaderChunk.cs (the ReadChunk method, version ≠ 3 branch).

Fields

patch_type: [u8; 4]

4-byte ASCII patch type tag, e.g. b"D000" for a game-data patch or b"H000" for a boot/header patch.

entry_files: u32

Number of SqPack entry files referenced by this patch.

This is an informational counter; the patcher does not use it to pre-allocate or validate anything at apply time.

Trait Implementations

impl BinRead for FileHeaderV2

type Args<'__binrw_generated_args_lifetime> = ()

The type used for the args parameter of read_args() and read_options().

fn read_options<R: Read + Seek>( __binrw_generated_var_reader: &mut R, __binrw_generated_var_endian: Endian, __binrw_generated_var_arguments: Self::Args<'_>, ) -> BinResult<Self>

Read Self from the reader using the given Endian and arguments.

fn read<R>(reader: &mut R) -> Result<Self, Error>

where R: Read + Seek, Self: ReadEndian, Self::Args<'a>: for<'a> Required,

Read Self from the reader using default arguments.

fn read_be<R>(reader: &mut R) -> Result<Self, Error>

where R: Read + Seek, Self::Args<'a>: for<'a> Required,

Read Self from the reader using default arguments and assuming big-endian byte order.

fn read_le<R>(reader: &mut R) -> Result<Self, Error>

where R: Read + Seek, Self::Args<'a>: for<'a> Required,

Read Self from the reader using default arguments and assuming little-endian byte order.

fn read_ne<R>(reader: &mut R) -> Result<Self, Error>

where R: Read + Seek, Self::Args<'a>: for<'a> Required,

Read T from the reader assuming native-endian byte order.

fn read_args<R>(reader: &mut R, args: Self::Args<'_>) -> Result<Self, Error>

where R: Read + Seek, Self: ReadEndian,

Read Self from the reader using the given arguments.

fn read_be_args<R>(reader: &mut R, args: Self::Args<'_>) -> Result<Self, Error>

where R: Read + Seek,

Read Self from the reader, assuming big-endian byte order, using the given arguments.

fn read_le_args<R>(reader: &mut R, args: Self::Args<'_>) -> Result<Self, Error>

where R: Read + Seek,

Read Self from the reader, assuming little-endian byte order, using the given arguments.

fn read_ne_args<R>(reader: &mut R, args: Self::Args<'_>) -> Result<Self, Error>

where R: Read + Seek,

Read T from the reader, assuming native-endian byte order, using the given arguments.

impl Clone for FileHeaderV2

fn clone(&self) -> FileHeaderV2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileHeaderV2

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

Formats the value using the given formatter.

impl PartialEq for FileHeaderV2

fn eq(&self, other: &FileHeaderV2) -> 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.

impl ReadEndian for FileHeaderV2

const ENDIAN: EndianKind

The endianness of the type.
