Struct BlockDisassembler 

pub struct BlockDisassembler { /* private fields */ }

Splits a response payload into Block2 chunks for incremental delivery.

RFC 7959 §2.4: The server sends the first block proactively, then the client requests subsequent blocks by including a Block2 option with the desired block number.

Implementations

impl BlockDisassembler

pub fn new(payload: Vec<u8>, szx: u8) -> Self

Creates a new disassembler for the given payload and block size.

Arguments

• payload - Complete response payload to split into blocks.
• szx - Block size exponent. Clamped to MAX_SZX.

pub fn get_block(&self, block_num: u32) -> Option<(Vec<u8>, BlockOption)>

Returns the block data and corresponding Block2 option for the given block number.

Returns None if block_num is beyond the last block.

pub fn total_blocks(&self) -> u32

Returns the total number of blocks required for this payload.

pub fn payload_len(&self) -> usize

Returns the full payload length in bytes.

pub fn szx(&self) -> u8

Returns the block size exponent.
