Enum smoltcp::wire::IpRepr

pub enum IpRepr {
    Ipv4(Ipv4Repr),
    Ipv6(Ipv6Repr),
}

An IP packet representation.

This enum abstracts the various versions of IP packets. It either contains an IPv4 or IPv6 concrete high-level representation.

Variants

Ipv4(Ipv4Repr)

Ipv6(Ipv6Repr)

Implementations

impl Repr

pub fn new( src_addr: Address, dst_addr: Address, next_header: Protocol, payload_len: usize, hop_limit: u8 ) -> Self

Create a new IpRepr, choosing the right IP version for the src/dst addrs.

Panics

Panics if src_addr and dst_addr are different IP version.

pub const fn version(&self) -> Version

Return the protocol version.

pub const fn src_addr(&self) -> Address

Return the source address.

pub const fn dst_addr(&self) -> Address

Return the destination address.

pub const fn next_header(&self) -> Protocol

Return the next header (protocol).

pub const fn payload_len(&self) -> usize

Return the payload length.

pub fn set_payload_len(&mut self, length: usize)

Set the payload length.

pub const fn hop_limit(&self) -> u8

Return the TTL value.

pub const fn header_len(&self) -> usize

Return the length of a header that will be emitted from this high-level representation.

pub fn emit<T: AsRef<[u8]> + AsMut<[u8]>>( &self, buffer: T, _checksum_caps: &ChecksumCapabilities )

Emit this high-level representation into a buffer.

pub const fn buffer_len(&self) -> usize

Return the total length of a packet that will be emitted from this high-level representation.

This is the same as repr.buffer_len() + repr.payload_len().

Trait Implementations

impl Clone for Repr

fn clone(&self) -> Repr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Repr

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

Formats the value using the given formatter.

impl From<Repr> for Repr

fn from(repr: Ipv4Repr) -> Repr

Converts to this type from the input type.

impl From<Repr> for Repr

fn from(repr: Ipv6Repr) -> Repr

Converts to this type from the input type.

impl PartialEq for Repr

fn eq(&self, other: &Repr) -> 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.
