Struct smoltcp::wire::Ipv6Option

pub struct Ipv6Option<T: AsRef<[u8]>> { /* private fields */ }

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

Implementations

impl<T: AsRef<[u8]>> Ipv6Option<T>

pub const fn new_unchecked(buffer: T) -> Ipv6Option<T>

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

pub fn new_checked(buffer: T) -> Result<Ipv6Option<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) if the buffer is too short.

The result of this check is invalidated by calling set_data_len.

pub fn into_inner(self) -> T

Consume the ipv6 option, returning the underlying buffer.

pub fn option_type(&self) -> Type

Return the option type.

pub fn data_len(&self) -> u8

Return the length of the data.

Panics

This function panics if this is an 1-byte padding option.

impl<'a, T: AsRef<[u8]> + ?Sized> Ipv6Option<&'a T>

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

Return the option data.

Panics

This function panics if this is an 1-byte padding option.

impl<T: AsRef<[u8]> + AsMut<[u8]>> Ipv6Option<T>

pub fn set_option_type(&mut self, value: Type)

Set the option type.

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

Set the option data length.

Panics

This function panics if this is an 1-byte padding option.

impl<'a, T: AsRef<[u8]> + AsMut<[u8]> + ?Sized> Ipv6Option<&'a mut T>

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

Return a mutable pointer to the option data.

Panics

This function panics if this is an 1-byte padding option.

Trait Implementations

impl<T: Debug + AsRef<[u8]>> Debug for Ipv6Option<T>

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

Formats the value using the given formatter.

impl<'a, T: AsRef<[u8]> + ?Sized> Display for Ipv6Option<&'a T>

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

Formats the value using the given formatter.

impl<T: PartialEq + AsRef<[u8]>> PartialEq<Ipv6Option<T>> for Ipv6Option<T>

fn eq(&self, other: &Ipv6Option<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.
