Struct DeltaDecoder 

pub struct DeltaDecoder { /* private fields */ }

Parse fragmented, already inflated delta bytes with fixed inline state. The trusted base must be canonical and completely resolved at base_depth. Copies use 64-bit ranges so the host can await bounded storage reads between events. Inserts borrow the current input, including partial instructions.

Output is provisional: the caller must execute all events, hash the result with its inherited object kind, and validate the enclosing pack and graph before publishing refs. position counts emitted bytes, not successful I/O.

Implementations

impl DeltaDecoder

pub fn new(base_size: u64, base_depth: u32, limits: DeltaLimits) -> Result<Self>

pub fn position(&self) -> u64

pub fn depth(&self) -> u32

pub fn update<'input>( &mut self, input: &'input [u8], end_of_input: bool, ) -> Result<DeltaProgress<'input>>

Return at most one event. Resubmit the unconsumed suffix, retaining its EOF flag; end_of_input closes the delta, not merely this input chunk. Failures are terminal. Exact EOF is required, including an empty call after the last instruction if its event consumed the final input byte.

pub fn finish(&self) -> Result<()>
