Struct SixlowpanUdpNhcPacket 

pub struct SixlowpanUdpNhcPacket<T: AsRef<[u8]>> { /* private fields */ }

A read/write wrapper around a 6LoWPAN_NHC UDP frame. RFC 6282 § 4.3 specifies the format of the header.

The base header has the following format:

  0   1   2   3   4   5   6   7
+---+---+---+---+---+---+---+---+
| 1 | 1 | 1 | 1 | 0 | C |   P   |
+---+---+---+---+---+---+---+---+
With:
- C: checksum, specifies if the checksum is elided.
- P: ports, specifies if the ports are elided.

Implementations

impl<T: AsRef<[u8]>> UdpNhcPacket<T>

pub const fn new_unchecked(buffer: T) -> Self

Input a raw octet buffer with a LOWPAN_NHC frame structure for UDP.

pub fn new_checked(buffer: T) -> Result<Self>

Shorthand for a combination of new_unchecked and check_len.

pub fn check_len(&self) -> Result<()>

Ensure that no accessor method will panic if called. Returns Err(Error::Truncated) if the buffer is too short.

pub fn into_inner(self) -> T

Consumes the frame, returning the underlying buffer.

pub fn src_port(&self) -> u16

Return the source port number.

pub fn dst_port(&self) -> u16

Return the destination port number.

pub fn checksum(&self) -> Option<u16>

Return the checksum.

impl<'a, T: AsRef<[u8]> + ?Sized> UdpNhcPacket<&'a T>

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

Return a pointer to the payload.

impl<T: AsRef<[u8]> + AsMut<[u8]>> UdpNhcPacket<T>

pub fn payload_mut(&mut self) -> &mut [u8]

Return a mutable pointer to the payload.

Trait Implementations

impl<T: Clone + AsRef<[u8]>> Clone for UdpNhcPacket<T>

fn clone(&self) -> UdpNhcPacket<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + AsRef<[u8]>> Debug for UdpNhcPacket<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
