Module utils 

Shared pack-parsing helpers for reading object headers, varints, offsets, and zlib-compressed payloads as defined by Git’s pack format.

Functions

calculate_object_hash

Calculate the SHA1 hash of the given object.
“<type> <size>\0<content>”
data: The decompressed content of the object

count_dir_files

Count the number of files in a directory and its subdirectories.

create_empty_dir

Create an empty directory or clear the existing directory.

is_eof

Checks if the reader has reached EOF (end of file).

read_byte_and_check_continuation

Reads a byte from the given stream and checks if there are more bytes to continue reading.

read_bytes

Read the next N bytes from the reader

read_delta_object_size

Reads the base size and result size of a delta object from the given stream.

read_offset_encoding

The offset for an OffsetDelta object(big-endian order)

read_partial_int

Reads a partial integer from a stream. (little-endian order)

read_type_and_varint_size

Reads bytes from the stream and parses the first byte for type and size. Subsequent bytes are read as size bytes and are processed as variable-length integer in little-endian order. The function returns the type and the computed size.

read_varint_le

Reads a variable-length integer (VarInt) encoded in little-endian format from a source implementing the Read trait.
