ChunkList

Struct ChunkList 

Source
pub struct ChunkList(/* private fields */);
Expand description

Sender side: an ordered list of Chunks for one message. Build it from the payload with ChunkList::split, passing the per-message data size to cut at (the connection’s negotiated max_message_size minus the envelope reserve), then iterate (or convert to Vec<Chunk>) to put each chunk on the wire. The cut size is a runtime argument rather than a type parameter because it is decided per connection from the negotiated limit. Reassembly is the receiver’s job — see MessageReassembler.

Implementations§

Source§

impl ChunkList

Source

pub fn split(bytes: &Bytes, chunk_size: usize) -> Self

Eagerly split bytes into chunks of at most chunk_size data bytes each, tagged [i, total]. A test/helper constructor (the production send path uses stream, and WireReserves::plan never yields an unusable chunk_size — it returns None instead). chunk_size is clamped to ≥ 1 only as a defensive guard against a caller passing 0; it is not a sanctioned way to produce 1-byte chunks on the wire.

Source

pub fn stream(bytes: Bytes, chunk_size: usize) -> impl Iterator<Item = Chunk>

Stream bytes into chunks of at most chunk_size data bytes each without materializing the whole list: each chunk’s data is a zero-copy Bytes::slice of the input, and the chunks are yielded lazily, so a sender can frame and flush one chunk at a time with bounded memory (rather than allocating every chunk up front). All chunks share one [i, total] numbering and one ChunkMeta. chunk_size is clamped to ≥ 1 so a degenerate value still terminates; empty input yields no chunks, agreeing with split.

Source

pub fn to_vec(&self) -> Vec<Chunk>

Clone out the chunks.

Source

pub fn as_vec(&self) -> &Vec<Chunk>

Borrow the chunks.
