Struct StreamObjectLayout 

pub struct StreamObjectLayout { /* private fields */ }

Delimits sealed stream chunks without buffering the object. The caller reserves the final 64 bytes for the whole-object signature. Acceptance also requires that signature and the plaintext decoder’s end-marker check.

Implementations

impl StreamObjectLayout

pub fn new() -> Self

Start the stream’s section 0 at chunk index 0.

pub fn index(&self) -> u64

The index to authenticate when sealing or opening the next chunk.

pub fn chunk_length(&self, prefix: &[u8]) -> Result<usize, Error>

Bound a length prefix before fetching or allocating its chunk.

pub fn encode_chunk(&mut self, bytes: &[u8]) -> Result<Vec<u8>, Error>

Encode one sealed chunk, checking the canonical chunk partition.

pub fn decode_chunk<'a>(&mut self, piece: &'a [u8]) -> Result<&'a [u8], Error>

Read a complete length-prefixed chunk without copying its sealed bytes.

pub fn read_signature(self, bytes: &[u8]) -> Result<Signature, Error>

Consume the layout at its final signature, requiring at least one chunk. The caller verifies it against the digest of every preceding object byte, including the prefix signature, before applying any plaintext.

Trait Implementations

impl Default for StreamObjectLayout

fn default() -> Self

Returns the “default value” for a type.
