Implementations

impl TransportHeader

pub fn udp(self) -> Option<UdpHeader>

Returns Result::Some containing the udp header if self has the value Udp. Otherwise None is returned.

pub fn mut_udp(&mut self) -> Option<&mut UdpHeader>

Returns Result::Some containing the udp header if self has the value Udp. Otherwise None is returned.

pub fn tcp(self) -> Option<TcpHeader>

Returns Result::Some containing the tcp header if self has the value Tcp. Otherwise None is returned.

pub fn mut_tcp(&mut self) -> Option<&mut TcpHeader>

Returns Result::Some containing a mutable reference to the tcp header if self has the value Tcp. Otherwise None is returned.

pub fn icmpv4(self) -> Option<Icmpv4Header>

Returns Result::Some containing the ICMPv4 header if self has the value Icmpv4. Otherwise None is returned.

pub fn mut_icmpv4(&mut self) -> Option<&mut Icmpv4Header>

Returns Result::Some containing the ICMPv4 header if self has the value Icmpv4. Otherwise None is returned.

pub fn icmpv6(self) -> Option<Icmpv6Header>

Returns Result::Some containing the ICMPv6 header if self has the value Icmpv6. Otherwise None is returned.

pub fn mut_icmpv6(&mut self) -> Option<&mut Icmpv6Header>

Returns Result::Some containing the ICMPv6 header if self has the value Icmpv6. Otherwise None is returned.

pub fn header_len(&self) -> usize

Returns the size of the transport header (in case of UDP fixed, in case of TCP cotanining the options).

pub fn update_checksum_ipv4( &mut self, ip_header: &Ipv4Header, payload: &[u8] ) -> Result<(), TransportChecksumError>

Calculates the checksum for the transport header & sets it in the header for an ipv4 header.

pub fn update_checksum_ipv6( &mut self, ip_header: &Ipv6Header, payload: &[u8] ) -> Result<(), ValueTooBigError<usize>>

Calculates the checksum for the transport header & sets it in the header for an ipv6 header.

pub fn write<T: Write + Sized>(&self, writer: &mut T) -> Result<(), Error>

Available on crate feature std only.

Write the transport header to the given writer.

Trait Implementations

impl Clone for TransportHeader

fn clone(&self) -> TransportHeader

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransportHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TransportHeader

fn eq(&self, other: &TransportHeader) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
