Struct SqpkCompressedBlock 

pub struct SqpkCompressedBlock { /* private fields */ }

One DEFLATE-or-raw block of a SqpkFile payload.

Implementations

impl SqpkCompressedBlock

pub fn new(is_compressed: bool, decompressed_size: usize, data: Vec<u8>) -> Self

Build a block from its parsed parts (test/external use).

pub fn decompress_into(&self, w: &mut impl Write) -> Result<()>

Stream the block’s decompressed bytes into w.

Uncompressed blocks are written verbatim; compressed blocks are run through a DEFLATE decoder. Returns ZiPatchError::Decompress on a decompression error.

pub fn decompress(&self) -> Result<Cow<'_, [u8]>>

Return the block’s decompressed bytes.

Uncompressed blocks return a borrow into the existing buffer with no allocation; compressed blocks allocate and decompress into a new Vec.

Trait Implementations

impl Clone for SqpkCompressedBlock

fn clone(&self) -> SqpkCompressedBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqpkCompressedBlock

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

Formats the value using the given formatter.

impl PartialEq for SqpkCompressedBlock

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