Struct smoltcp::wire::Ipv6HopByHopHeader

pub struct Ipv6HopByHopHeader<T: AsRef<[u8]>> { /* private fields */ }

A read/write wrapper around an IPv6 Hop-by-Hop Options Header.

Implementations

impl<T: AsRef<[u8]>> Header<T>

pub fn new_unchecked(buffer: T) -> Header<T>

Create a raw octet buffer with an IPv6 Hop-by-Hop Options Header structure.

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

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::Truncated) 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) -> Protocol

Return the next header field.

pub fn header_len(&self) -> u8

Return length of the Hop-by-Hop Options header in 8-octet units, not including the first 8 octets.

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

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

Return the option data.

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

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

Set the next header field.

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

Set the option data length. Length of the Hop-by-Hop Options header in 8-octet units, not including the first 8 octets.

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

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

Return a mutable pointer to the option 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<'a, T: AsRef<[u8]> + ?Sized> Display for Header<&'a T>

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

Formats the value using the given formatter.

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

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