Struct PackStreamScanner 

pub struct PackStreamScanner { /* private fields */ }

Incremental object counter over a pack byte stream.

Feed it the pack’s bytes in order, starting at the PACK signature, in chunks of any size; Self::counts reports how many entries have been fully received.

Implementations

impl PackStreamScanner

pub fn new(hash: HashAlgo) -> Self

Create a scanner for a pack whose REF_DELTA bases are hash ids.

Parameters

• hash: the object format of the pack (decides the length of a REF_DELTA entry’s base id).

pub fn counts(&self) -> Option<ReceivedObjects>

Objects received so far, or None until the pack header has arrived.

pub fn is_complete(&self) -> bool

Whether every object named in the pack header has been received.

pub fn feed(&mut self, data: &[u8]) -> Result<(), PackStreamScanError>

Scan the next data bytes of the pack.

Parameters

• data: the bytes that follow everything fed so far.

Errors

Returns a PackStreamScanError when the bytes are not a well-formed pack. The scanner should be discarded after an error.
