Struct Ipv6ExtHeader

pub struct Ipv6ExtHeader<T: AsRef<[u8]>> { /* private fields */ }

A read/write wrapper around an IPv6 Extension Header buffer.

Implementations

impl<T: AsRef<[u8]>> Header<T>

Core getter methods relevant to any IPv6 extension header.

pub const fn new_unchecked(buffer: T) -> Self

Create a raw octet buffer with an IPv6 Extension Header structure.

pub fn new_checked(buffer: T) -> Result<Self>

Shorthand for a combination of new_unchecked and check_len.

pub fn check_len(&self) -> Result<()>

Ensure that no accessor method will panic if called. Returns Err(Error) if the buffer is too short.

The result of this check is invalidated by calling set_header_len.

pub fn into_inner(self) -> T

Consume the header, returning the underlying buffer.

pub fn next_header(&self) -> IpProtocol

Return the next header field.

pub fn header_len(&self) -> u8

Return the header length field.

impl<'h, T: AsRef<[u8]> + ?Sized> Header<&'h T>

pub fn payload(&self) -> &'h [u8]

Return the payload of the IPv6 extension header.

impl<T: AsRef<[u8]> + AsMut<[u8]>> Header<T>

pub fn set_next_header(&mut self, value: IpProtocol)

Set the next header field.

pub fn set_header_len(&mut self, value: u8)

Set the extension header data length. The length of the header is in 8-octet units, not including the first 8 octets.

impl<'a, T: AsRef<[u8]> + AsMut<[u8]> + ?Sized> Header<&'a mut T>

pub fn payload_mut(&mut self) -> &mut [u8]

Return a mutable pointer to the payload data.

Trait Implementations

impl<T: Debug + AsRef<[u8]>> Debug for Header<T>

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

Formats the value using the given formatter.

impl<T: PartialEq + AsRef<[u8]>> PartialEq for Header<T>

fn eq(&self, other: &Header<T>) -> 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.
