Struct CnMsg

pub struct CnMsg<P: Size> { /* private fields */ }

Netlink connector message header and payload.

Implementations

impl<P: Size> CnMsg<P>

pub fn idx(&self) -> &CnMsgIdx

Index of the connector (idx)

pub fn val(&self) -> &CnMsgVal

Value (val)

pub fn seq(&self) -> &u32

Sequence number

pub fn ack(&self) -> &u32

Acknowledgement number

pub fn len(&self) -> &u16

Length of the payload

pub fn flags(&self) -> &u16

Flags

pub fn payload(&self) -> &P

Payload of the netlink message

You can either use predefined types like ProcCnMcastOp or ProcEventHeader, a custom type defined by you or Vec<u8> for raw payload.

Trait Implementations

impl<P: Clone + Size> Clone for CnMsg<P>

fn clone(&self) -> CnMsg<P>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<P: Debug + Size> Debug for CnMsg<P>

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

Formats the value using the given formatter.

impl<P: Size + FromBytesWithInput<Input = usize>> FromBytesWithInput for CnMsg<P>

type Input = usize

The type of the additional input.

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

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

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

Strip padding from a netlink message.

impl<P: Size> Header for CnMsg<P>

fn header_size() -> usize

Return the size in bytes of the data structure header.

impl<P: PartialEq + Size> PartialEq for CnMsg<P>

fn eq(&self, other: &CnMsg<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<P: Size + Size> Size for CnMsg<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<P: Size + ToBytes> ToBytes for CnMsg<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.
