Struct ChunkWriter 

pub struct ChunkWriter { /* private fields */ }

Stateless-per-message outbound chunk writer (§5.3): serializes a Message into chunk bytes at the current chunk size.

Simple, always-correct strategy: the first chunk is always Type 0 (full absolute-timestamp header) and every continuation chunk is Type 3 (0-byte header, inheriting everything). This is spec-valid — Type 1/2’s more compact delta-based headers are a size optimisation this writer does not perform.

Implementations

impl ChunkWriter

pub fn new() -> Self

New writer, chunk size at the §5.3 default (128 bytes).

pub fn set_chunk_size(&mut self, n: u32)

Update the chunk size used for subsequent ChunkWriter::write calls (called on sending a Set Chunk Size protocol control message, §5.4.1). Capped at MAX_CHUNK_SIZE (the floor-of-1 is applied in ChunkWriter::write itself).

pub fn write(&mut self, msg: &Message) -> Vec<u8>

Serialize msg into chunk bytes at the current chunk size: a Type 0 first chunk carrying up to chunk_size payload bytes, then Type 3 continuation chunks for the remainder.

Panics

If msg.chunk_stream_id is outside the basic header’s encodable range (2..=65599) — the same precondition BasicHeader::serialize_into enforces. Every chunk_stream_id produced by ChunkAssembler::push satisfies this (BasicHeader::parse never yields one outside the range), so a Message round-tripped from the assembler never panics here; callers building a Message from scratch must respect it.
