Struct Nlmsghdr

pub struct Nlmsghdr<T, P> { /* private fields */ }

Top level netlink header and payload

Implementations

impl<T, P> Nlmsghdr<T, P>

pub fn nl_len(&self) -> &u32

Length of the netlink message

pub fn nl_type(&self) -> &T

Type of the netlink message

pub fn nl_flags(&self) -> &NlmF

Flags indicating properties of the request or response

pub fn nl_seq(&self) -> &u32

Sequence number for netlink protocol

pub fn nl_pid(&self) -> &u32

ID of the netlink destination for requests and source for responses.

pub fn nl_payload(&self) -> &NlPayload<T, P>

Payload of netlink message

impl<T, P> Nlmsghdr<T, P>

where T: NlType,

pub fn get_payload(&self) -> Option<&P>

Get the payload if there is one or return an error.

pub fn get_err(&mut self) -> Option<Nlmsgerr<NlmsghdrErr<T, P>>>

Get an error from the payload if it exists.

Takes a mutable reference because the payload will be swapped for Empty to gain ownership of the error.

impl<T, P> Nlmsghdr<T, P>

where T: NlType, P: Size,

pub fn set_payload(&mut self, p: NlPayload<T, P>)

Set the payload for Nlmsghdr and handle the change in length internally.

impl Nlmsghdr<u16, Buffer>

pub fn to_typed<T, P>(self) -> Result<Nlmsghdr<T, P>, RouterError<T, P>>

where T: NlType, P: Size + FromBytesWithInput<Input = usize>,

Set the payload for Nlmsghdr and handle the change in length internally.

Trait Implementations

impl<T: Clone, P: Clone> Clone for Nlmsghdr<T, P>

fn clone(&self) -> Nlmsghdr<T, P>

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

impl<T: NlType, P: Size + FromBytesWithInput<Input = usize>> FromBytes for Nlmsghdr<T, P>

fn from_bytes(buffer: &mut Cursor<impl AsRef<[u8]>>) -> Result<Self, DeError>

Takes a byte buffer and returns the deserialized data structure.

fn strip(buffer: &mut Cursor<impl AsRef<[u8]>>) -> Result<(), DeError>

Strip padding from a netlink message.

impl<T, P> FromIterator<Nlmsghdr<T, P>> for NlBuffer<T, P>

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

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

Creates a value from an iterator.

impl<T: TypeSize, P> Header for Nlmsghdr<T, P>

fn header_size() -> usize

Return the size in bytes of the data structure header.

impl<T: PartialEq, P: PartialEq> PartialEq for Nlmsghdr<T, P>

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

impl<T: Size, P: Size> Size for Nlmsghdr<T, P>

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 the payload and align it to the required netlink byte alignment.

impl<T: ToBytes, P: ToBytes> ToBytes for Nlmsghdr<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.
