Struct RtBuffer

pub struct RtBuffer<T, P>(/* private fields */);

A buffer of rtnetlink attributes.

Implementations

impl<T> RtBuffer<T, Buffer>

pub fn get_attr_handle(&self) -> AttrHandle<'_, Self, Rtattr<T, Buffer>>

impl<T, P> RtBuffer<T, P>

pub fn new() -> Self

Create a new buffer of routing netlink attributes.

pub fn push(&mut self, attr: Rtattr<T, P>)

Add a new routing netlink attribute to the end of the buffer.

pub fn pop(&mut self) -> Option<Rtattr<T, P>>

Get a routing netlink attribute from the end of the buffer.

pub fn iter(&self) -> Iter<'_, Rtattr<T, P>>

Return an iterator over immutable references to the elements in the buffer.

pub fn iter_mut(&mut self) -> IterMut<'_, Rtattr<T, P>>

Return an iterator over mutable references to the elements in the buffer.

pub fn len(&self) -> usize

Returns the number of elements in the buffer.

pub fn is_empty(&self) -> bool

Returns whether the number of elements in the buffer is 0.

Trait Implementations

impl<T, P> AsMut<[Rtattr<T, P>]> for RtBuffer<T, P>

fn as_mut(&mut self) -> &mut [Rtattr<T, P>]

Converts this type into a mutable reference of the (usually inferred) input type.

impl<T, P> AsRef<[Rtattr<T, P>]> for RtBuffer<T, P>

fn as_ref(&self) -> &[Rtattr<T, P>]

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Debug, P: Debug> Debug for RtBuffer<T, P>

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

Formats the value using the given formatter.

impl<T, P> Default for RtBuffer<T, P>

fn default() -> Self

Returns the “default value” for a type.

impl<'lifetime, T: RtaType, P: FromBytesWithInput<'lifetime, Input = usize>> FromBytesWithInput<'lifetime> for RtBuffer<T, P>

type Input = usize

The type of the additional input.

fn from_bytes_with_input( buffer: &mut Cursor<&'lifetime [u8]>, input: Self::Input, ) -> Result<Self, DeError>

Takes a byte buffer and an additional input and returns the deserialized data structure.

impl<T, P> FromIterator<Rtattr<T, P>> for RtBuffer<T, P>

fn from_iter<I>(i: I) -> Self

where I: IntoIterator<Item = Rtattr<T, P>>,

Creates a value from an iterator.

impl<T, P> IntoIterator for RtBuffer<T, P>

type Item = Rtattr<T, P>

The type of the elements being iterated over.

type IntoIter = <Vec<Rtattr<T, P>> as IntoIterator>::IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T, P> Size for RtBuffer<T, P>

where T: Size, P: Size,

fn unpadded_size(&self) -> usize

Size of the unpadded data structure. This will usually only be unaligned for variable length types like strings or byte buffers.

fn padded_size(&self) -> usize

Get the size of of the payload and align it to the required netlink byte alignment.

impl<T: ToBytes, P: ToBytes> ToBytes for RtBuffer<T, P>

fn to_bytes(&self, buffer: &mut Cursor<Vec<u8>>) -> Result<(), SerError>

Takes a byte buffer and serializes the data structure into it.

fn pad(&self, buffer: &mut Cursor<Vec<u8>>) -> Result<(), SerError>

Pad a netlink message to the appropriate alignment.
