class PackChunkGenerator:

Constructor: PackChunkGenerator(object_format, num_records, records, progress, ...)

Generator for pack data chunks.

Method	`__init__`	Initialize PackChunkGenerator.
Method	`__iter__`	Iterate over pack data chunks.
Method	`sha1digest`	Return the SHA1 digest of the pack data.
Instance Variable	`cs`	Undocumented
Instance Variable	`entries`	Undocumented
Instance Variable	`object_format`	Undocumented
Method	`_pack_data_chunks`	Iterate pack data file chunks.
Instance Variable	`_it`	Undocumented

def __init__(self, object_format: ObjectFormat, num_records: int | None = None, records: Iterator[UnpackedObject] | None = None, progress: Callable[..., None] | None = None, compression_level: int = -1, reuse_compressed: bool = True): ¶

Initialize PackChunkGenerator.

Parameters
object_format:`ObjectFormat`	Object format (hash algorithm) to use
num_records:`int \| None`	Expected number of records
records:`Iterator[UnpackedObject] \| None`	Iterator of pack records
progress:`Callable[..., None] \| None`	Optional progress callback
compression_level:`int`	Compression level (-1 for default)
reuse_compressed:`bool`	Whether to reuse compressed chunks

def __iter__(self) -> Iterator[bytes]: ¶

Iterate over pack data chunks.

def sha1digest(self) -> bytes: ¶

Return the SHA1 digest of the pack data.

def _pack_data_chunks(self, records: Iterator[UnpackedObject], *, num_records: int | None = None, progress: Callable[..., None] | None = None, compression_level: int = -1, reuse_compressed: bool = True) -> Iterator[bytes]: ¶

Iterate pack data file chunks.

Returns: Dict mapping id -> (offset, crc32 checksum), pack checksum

Parameters
records:`Iterator[UnpackedObject]`	Iterator over UnpackedObject
num_records:`int \| None`	Number of records (defaults to len(records) if not specified)
progress:`Callable[..., None] \| None`	Function to report progress to
compression_level:`int`	the zlib compression level
reuse_compressed:`bool`	Whether to reuse compressed chunks

Returns
