Struct netsim_embed::ipv4::Ipv4Packet

pub struct Ipv4Packet<'p> { /* fields omitted */ }

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> Ipv4Packet<'a>

pub fn new(packet: &'p [u8]) -> Option<Ipv4Packet<'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, Global>) -> Option<Ipv4Packet<'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 self) -> Ipv4Packet<'p>

Maps from a #name to a #imm_name

pub fn consume_to_immutable(self) -> Ipv4Packet<'a>

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

pub const fn minimum_packet_size() -> usize

The minimum size (in bytes) a packet of this type can be. It’s based on the total size of the fixed-size fields.

pub fn packet_size(_packet: &Ipv4) -> usize

The size (in bytes) of a #base_name instance when converted into a byte-array

pub fn get_version(&self) -> u8

Get the version field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_header_length(&self) -> u8

Get the header_length field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_dscp(&self) -> u8

Get the dscp field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_ecn(&self) -> u8

Get the ecn field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_total_length(&self) -> u16

Get the total_length field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_identification(&self) -> u16

Get the identification field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_flags(&self) -> u8

Get the flags field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_fragment_offset(&self) -> u16

Get the fragment_offset field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_ttl(&self) -> u8

Get the ttl field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_next_level_protocol(&self) -> IpNextHeaderProtocol

Get the value of the {name} field

pub fn get_checksum(&self) -> u16

Get the checksum field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_source(&self) -> Ipv4Addr

Get the value of the {name} field

pub fn get_destination(&self) -> Ipv4Addr

Get the value of the {name} field

pub fn get_options_raw(&self) -> &[u8]

Get the raw &u8 value of the {name} field, without copying

pub fn get_options(&self) -> Vec<Ipv4Option, Global>

Get the value of the {name} field (copies contents)

pub fn get_options_iter(&self) -> Ipv4OptionIterable<'_>

Get the value of the {name} field as iterator

pub fn get_payload(&self) -> Vec<u8, Global>

Get the value of the {name} field (copies contents)
