Struct FileChunker 

pub struct FileChunker { /* private fields */ }

Streaming content-addressed chunker.

Construct one via FileChunker::new, push bytes with FileChunker::write, and call FileChunker::finalize to get the root address. Optionally pass an on_chunk callback to FileChunker::with_callback to be notified as each chunk is sealed (useful for streaming uploads).

Implementations

impl FileChunker

pub fn new() -> Self

New chunker without an on-chunk callback. Use this for offline hashing.

pub fn with_callback<F>(callback: F) -> Self

where F: FnMut(SealedChunk) -> Result<(), Error> + Send + 'static,

New chunker with an on-chunk callback. The callback runs synchronously as each leaf or intermediate chunk is sealed.

pub fn write(&mut self, data: &[u8]) -> Result<usize, Error>

Append bytes to the input stream. As each leaf reaches CHUNK_SIZE it is sealed and propagated up the level stack.

pub fn finalize(self) -> Result<ChunkerRoot, Error>

Seal any trailing partial leaf, collapse the level stack, and return the root chunk’s address + span. An empty chunker (zero bytes written) is rejected as it has no valid root.

Trait Implementations

impl Default for FileChunker

fn default() -> Self

Returns the “default value” for a type.
