Enum IpHeadersSlice 

pub enum IpHeadersSlice<'a> {
    Ipv4(Ipv4HeaderSlice<'a>, Ipv4ExtensionsSlice<'a>),
    Ipv6(Ipv6HeaderSlice<'a>, Ipv6ExtensionsSlice<'a>),
}

Slice containing an IPv4 or IPv6 base header plus extension headers.

Variants

Ipv4(Ipv4HeaderSlice<'a>, Ipv4ExtensionsSlice<'a>)

IPv4 base header and extension headers.

Ipv6(Ipv6HeaderSlice<'a>, Ipv6ExtensionsSlice<'a>)

IPv6 base header and extension headers.

Implementations

impl<'a> IpHeadersSlice<'a>

pub fn is_ipv4(&self) -> bool

Returns true if the slice contains an IPv4 header.

pub fn is_ipv6(&self) -> bool

Returns true if the slice contains an IPv6 header.

pub fn ipv4(&self) -> Option<Ipv4HeaderSlice<'a>>

Returns the IPv4 header slice if self contains one.

pub fn ipv4_exts(&self) -> Option<Ipv4ExtensionsSlice<'a>>

Returns the IPv4 extension header slices if self contains one.

pub fn ipv6(&self) -> Option<Ipv6HeaderSlice<'a>>

Returns the IPv6 header slice if self contains one.

pub fn ipv6_exts(&self) -> Option<&Ipv6ExtensionsSlice<'a>>

Returns the IPv6 extension header slices if self contains one.

pub fn slice(&self) -> &'a [u8]

Returns the underlying base-header slice.

pub fn source_addr(&self) -> IpAddr

Returns the source IP address.

pub fn destination_addr(&self) -> IpAddr

Returns the destination IP address.

pub fn next_header(&self) -> IpNumber

Returns the protocol number stored in the base header.

For IPv4 this is the protocol field and for IPv6 this is the next_header field.

pub fn payload_ip_number(&self) -> IpNumber

Returns the payload IP number after extension headers.

pub fn version(&self) -> u8

Returns the IP version (4 or 6).

pub fn header_len(&self) -> usize

Returns the serialized header length in bytes, including extensions.

pub fn try_to_header(&self) -> Result<IpHeaders, HeaderSliceError>

Converts this sliced header representation into IpHeaders.

For IPv6 this conversion uses Ipv6Extensions::from_slice.

Note that Ipv6Extensions can only represent a subset of valid IPv6 extension chains. If more extension headers are present than can be represented, only the representable subset is converted.

Trait Implementations

impl<'a> Clone for IpHeadersSlice<'a>

fn clone(&self) -> IpHeadersSlice<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for IpHeadersSlice<'a>

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

Formats the value using the given formatter.

impl<'a> From<(Ipv4HeaderSlice<'a>, Ipv4ExtensionsSlice<'a>)> for IpHeadersSlice<'a>

fn from(value: (Ipv4HeaderSlice<'a>, Ipv4ExtensionsSlice<'a>)) -> Self

Converts to this type from the input type.

impl<'a> From<(Ipv6HeaderSlice<'a>, Ipv6ExtensionsSlice<'a>)> for IpHeadersSlice<'a>

fn from(value: (Ipv6HeaderSlice<'a>, Ipv6ExtensionsSlice<'a>)) -> Self

Converts to this type from the input type.

impl<'a> From<Ipv4HeaderSlice<'a>> for IpHeadersSlice<'a>

fn from(value: Ipv4HeaderSlice<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<Ipv6HeaderSlice<'a>> for IpHeadersSlice<'a>

fn from(value: Ipv6HeaderSlice<'a>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for IpHeadersSlice<'a>

fn eq(&self, other: &IpHeadersSlice<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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