Implementations

impl DoubleVlanHeader

pub const LEN: usize = 8usize

Serialized size of two VLAN headers in bytes/octets.

pub const SERIALIZED_SIZE: usize = 8usize

👎Deprecated since 0.14.0: Use DoubleVlanHeader::LEN instead

pub fn read_from_slice( slice: &[u8] ) -> Result<(DoubleVlanHeader, &[u8]), HeaderSliceError>

👎Deprecated since 0.10.1: Use SingleVlanHeader::from_slice instead.

Read an DoubleVlanHeader from a slice and return the header & unused parts of the slice.

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

Read an DoubleVlanHeader from a slice and return the header & unused parts of the slice.

pub fn read<T: Read + Seek + Sized>( reader: &mut T ) -> Result<DoubleVlanHeader, HeaderReadError>

Available on crate feature std only.

Read a double tagging header from the given source

pub fn write<T: Write + Sized>(&self, writer: &mut T) -> Result<(), Error>

Available on crate feature std only.

Write the double IEEE 802.1Q VLAN tagging header

pub fn header_len(&self) -> usize

Length of the serialized headers in bytes.

pub fn to_bytes(&self) -> [u8; 8]

Returns the serialized form of the headers or an value error in case the headers contain values that are outside of range.

Trait Implementations

impl Clone for DoubleVlanHeader

fn clone(&self) -> DoubleVlanHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DoubleVlanHeader

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

Formats the value using the given formatter.

impl Default for DoubleVlanHeader

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DoubleVlanHeader

fn eq(&self, other: &DoubleVlanHeader) -> 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.
