Implementations

impl<'a> PacketReader<'a>

pub fn new(buffer: &'a [u8], size: u16) -> Self

pub fn position(&self) -> u16

pub fn remaining(&self) -> u16

pub fn can_read(&self, bytes: u16) -> bool

pub fn read_byte(&mut self) -> Result<u8>

pub fn read_u16(&mut self) -> Result<u16>

pub fn read_u32(&mut self) -> Result<u32>

pub fn read_bytes(&mut self, dest: &mut [u8]) -> Result<()>

pub fn skip(&mut self, count: u16) -> Result<()>

pub fn peek_byte(&self) -> Result<u8>

pub fn current_ptr(&self) -> &'a [u8]

pub fn parse_coap_header(&mut self) -> Result<CoAPHeader>

pub fn skip_token(&mut self, token_length: u8) -> Result<()>

pub fn parse_coap_option(&mut self) -> Result<(u16, u16, &'a [u8])>

Parse a single CoAP option. Returns (delta, length, value_slice).

pub fn parse_signet_options(&mut self) -> Result<SigNetOptions>

Parse all 6 SigNet options (2076–2236) from the current position. Stops at the payload marker (0xFF) — all options including HMAC must precede it. Leaves the reader positioned at the first byte of the payload.

pub fn parse_tlv_block(&mut self) -> Result<TLVBlock<'a>>

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