A read/write wrapper around an Internet Control Message Protocol version 6 packet buffer.

Implementations

impl<T> Packet<T>where T: AsRef<[u8]>,

pub const fn new_unchecked(buffer: T) -> Packet<T>

Imbue a raw octet buffer with ICMPv6 packet structure.

pub fn new_checked(buffer: T) -> Result<Packet<T>, Error>

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

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

pub fn into_inner(self) -> T

Consume the packet, returning the underlying buffer.
