Struct etherparse::IpAuthHeaderSlice

pub struct IpAuthHeaderSlice<'a> { /* private fields */ }

A slice containing an IP Authentication Header (rfc4302)

Implementations

impl<'a> IpAuthHeaderSlice<'a>

pub fn from_slice( slice: &'a [u8] ) -> Result<IpAuthHeaderSlice<'a>, HeaderSliceError>

Creates a ip authentication header slice from a slice.

pub unsafe fn from_slice_unchecked(slice: &'a [u8]) -> IpAuthHeaderSlice<'a>

Creates a ip authentication header slice from a slice (assumes slice size & content was validated before).

Safety

This method assumes that the slice was previously validated to contain a valid authentication header. This means the slice length must at least be at least 8 and (slice[1] + 2)*4. The data that the slice points must also be valid (meaning no nullptr or alike allowed).

If these preconditions are not fulfilled the behavior of this function and the methods of the return IpAuthHeaderSlice will be undefined.

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

Returns the slice containing the authentication header.

pub fn next_header(&self) -> IpNumber

Returns the IP protocol number of the next header or transport layer protocol.

See IpNumber or ip_number for a definition of the known values.

pub fn spi(&self) -> u32

Read the security parameters index from the slice

pub fn sequence_number(&self) -> u32

This unsigned 32-bit field contains a counter value that increases by one for each packet sent.

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

Return a slice with the raw integrity check value

pub fn to_header(&self) -> IpAuthHeader

Decode some of the fields and copy the results to a Ipv6ExtensionHeader struct together with a slice pointing to the non decoded parts.

Trait Implementations

impl<'a> Clone for IpAuthHeaderSlice<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for IpAuthHeaderSlice<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for IpAuthHeaderSlice<'a>

fn eq(&self, other: &IpAuthHeaderSlice<'a>) -> 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.
