Enum Chunk 

pub enum Chunk {
    FileHeader(FileHeader),
    ApplyOption(ApplyOption),
    ApplyFreeSpace(ApplyFreeSpace),
    AddDirectory(AddDirectory),
    DeleteDirectory(DeleteDirectory),
    Sqpk(SqpkCommand),
    EndOfFile,
}

One top-level chunk parsed from a ZiPatch stream.

Each variant corresponds to a 4-byte ASCII wire tag.

Observed frequency

SE’s XIVARR+ patch files almost exclusively contain FHDR, APLY, and SQPK chunks. ADIR/DELD can theoretically appear and are implemented, but are rarely emitted in practice. APFS has never been observed in modern patches and is treated as a no-op. EOF_ is consumed by ZiPatchReader and is never yielded to the caller.

Variants

FileHeader(FileHeader)

FHDR — the first chunk in every patch file; carries version and per-version patch metadata. See [FileHeader] for the versioned body.

ApplyOption(ApplyOption)

APLY — sets or clears a boolean apply-time flag on the crate::ApplyConfig (e.g. “ignore missing files”). See [ApplyOption].

ApplyFreeSpace(ApplyFreeSpace)

APFS — free-space book-keeping emitted by old patcher tooling; treated as a no-op at apply time. See [ApplyFreeSpace].

AddDirectory(AddDirectory)

ADIR — instructs the patcher to create a directory under the game install root. See [AddDirectory].

DeleteDirectory(DeleteDirectory)

DELD — instructs the patcher to remove a directory under the game install root. See [DeleteDirectory].

Sqpk(SqpkCommand)

SQPK — the workhorse chunk; wraps one of eight sub-commands that add, delete, expand, or replace SqPack data. See SqpkCommand.

EndOfFile

EOF_ — marks the clean end of the patch stream. ZiPatchReader consumes this chunk internally; it is never yielded to the caller.

Implementations

impl Chunk

pub fn apply(&self, session: &mut ApplySession) -> Result<()>

Trait Implementations

impl Debug for Chunk

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