Struct Chunks 

pub struct Chunks {
    pub ssn: u16,
    pub ppi: PayloadProtocolIdentifier,
    pub chunks: Vec<ChunkPayloadData>,
    /* private fields */
}

Chunks is a set of chunks that share the same SSN

Fields

ssn: u16

used only with the ordered chunks

ppi: PayloadProtocolIdentifier

The payload protocol identifier shared by every fragment of this message.

chunks: Vec<ChunkPayloadData>

The fragments, in order, that make up one complete message.

Implementations

impl Chunks

pub fn is_empty(&self) -> bool

Whether the reassembled message carries no bytes.

pub fn len(&self) -> usize

The total length in bytes of the reassembled message.

pub fn to_payload(&self, max_len: usize) -> Result<BytesMut>

Reassemble all fragments into a single freshly-allocated, exactly-sized buffer with one copy.

Unlike read, this does not round-trip through a caller-provided scratch buffer, eliminating one full-payload copy on the receive path (the reassembled message would otherwise be copied into the scratch buffer and then again into the delivered BytesMut). Returns Error::ErrShortBuffer when the message exceeds max_len, mirroring read’s bound so oversized inbound messages are still rejected.

pub fn read(&self, buf: &mut [u8]) -> Result<usize>

Concatenates every fragment into buf, returning the number of bytes written.

Errors

Returns Error::ErrShortBuffer if buf cannot hold the whole message; the partial copy is left in place.

pub fn next(&mut self, max_length: usize) -> Option<Chunk>

Yields the next slice of the reassembled message, up to max_length bytes.

Advances an internal cursor, so repeated calls walk the message; returns None once it is exhausted.
