Implementations§
source§impl<'a> Ipv4Packet<'a>
impl<'a> Ipv4Packet<'a>
sourcepub fn new<'p>(packet: &'p [u8]) -> Option<Ipv4Packet<'p>>
pub fn new<'p>(packet: &'p [u8]) -> Option<Ipv4Packet<'p>>
Constructs a new Ipv4Packet. If the provided buffer is less than the minimum required packet size, this will return None.
sourcepub fn owned(packet: Vec<u8>) -> Option<Ipv4Packet<'static>>
pub fn owned(packet: Vec<u8>) -> Option<Ipv4Packet<'static>>
Constructs a new Ipv4Packet. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the Ipv4Packet will own its own data and the underlying buffer will be dropped when the Ipv4Packet is.
sourcepub fn to_immutable<'p>(&'p self) -> Ipv4Packet<'p>
pub fn to_immutable<'p>(&'p self) -> Ipv4Packet<'p>
Maps from a Ipv4Packet to a Ipv4Packet
sourcepub fn consume_to_immutable(self) -> Ipv4Packet<'a>
pub fn consume_to_immutable(self) -> Ipv4Packet<'a>
Maps from a Ipv4Packet to a Ipv4Packet while consuming the source
sourcepub const fn minimum_packet_size() -> usize
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.
sourcepub fn packet_size(_packet: &Ipv4) -> usize
pub fn packet_size(_packet: &Ipv4) -> usize
The size (in bytes) of a Ipv4 instance when converted into a byte-array
sourcepub fn get_version(&self) -> u8
pub fn get_version(&self) -> u8
Get the version field.
sourcepub fn get_header_length(&self) -> u8
pub fn get_header_length(&self) -> u8
Get the header_length field.
sourcepub fn get_total_length(&self) -> u16
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.
sourcepub fn get_identification(&self) -> u16
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.
sourcepub fn get_fragment_offset(&self) -> u16
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.
sourcepub fn get_next_level_protocol(&self) -> IpNextHeaderProtocol
pub fn get_next_level_protocol(&self) -> IpNextHeaderProtocol
Get the value of the next_level_protocol field
sourcepub fn get_checksum(&self) -> u16
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.
sourcepub fn get_source(&self) -> Ipv4Addr
pub fn get_source(&self) -> Ipv4Addr
Get the value of the source field
sourcepub fn get_destination(&self) -> Ipv4Addr
pub fn get_destination(&self) -> Ipv4Addr
Get the value of the destination field
sourcepub fn get_options_raw(&self) -> &[u8] ⓘ
pub fn get_options_raw(&self) -> &[u8] ⓘ
Get the raw &u8 value of the options field, without copying
sourcepub fn get_options(&self) -> Vec<Ipv4Option>
pub fn get_options(&self) -> Vec<Ipv4Option>
Get the value of the options field (copies contents)
sourcepub fn get_options_iter(&self) -> Ipv4OptionIterable<'_> ⓘ
pub fn get_options_iter(&self) -> Ipv4OptionIterable<'_> ⓘ
Get the value of the options field as iterator
