Implementations

impl<'a> MutIpv4Packet<'a>

pub const MIN_LEN: usize = 20usize

The minimum number of bytes in this type of packet. Usually equal to the header size of the protocol.

pub fn new(data: &'a mut [u8]) -> Option<MutIpv4Packet<'a>>

Creates a new mutable packet based on the given backing slice. Returns None if the buffer is shorter than the minimal length of this packet.

pub unsafe fn new_unchecked(data: &'a mut [u8]) -> MutIpv4Packet<'a>

Creates a new mutable packet based on the given backing slice without checking its length first. If the slice is too short, a subsequent read from a field might result in invalid memory access.

pub fn as_immutable(&'a self) -> Ipv4Packet<'a>

Returns an immutable version of the same packet and backed by the same byte slice. Used to access the getters.

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

Returns a mutable reference to the slice backing this packet.

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

Returns a mutable slice to the part of the backing data that represents the header. This is simply everything up until min_len().

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

Returns a mutable slice to the payload part of the backing data. This is simply everything after the header.
