Implementations

impl<'a> MutableIpv4Packet<'a>

pub fn new<'p>(packet: &'p mut [u8]) -> Option<MutableIpv4Packet<'p>>

Constructs a new #name. If the provided buffer is less than the minimum required packet size, this will return None.

pub fn owned(packet: Vec<u8>) -> Option<MutableIpv4Packet<'static>>

Constructs a new #name. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the #name will own its own data and the underlying buffer will be dropped when the #name is.

pub fn to_immutable<'p>(&'p self) -> Ipv4Packet<'p>

Maps from a #name to a #imm_name

Maps from a #name to a #imm_name while consuming the source

pub const fn minimum_packet_size() -> usize
