Struct netlink_packet_core::header::NetlinkHeader

#[non_exhaustive]
pub struct NetlinkHeader {
    pub length: u32,
    pub message_type: u16,
    pub flags: u16,
    pub sequence_number: u32,
    pub port_number: u32,
}

A Netlink header representation. A netlink header has the following structure:

0                8                16              24               32
+----------------+----------------+----------------+----------------+
|                 packet length (including header)                  |
+----------------+----------------+----------------+----------------+
|          message type           |              flags              |
+----------------+----------------+----------------+----------------+
|                           sequence number                         |
+----------------+----------------+----------------+----------------+
|                   port number (formerly known as PID)             |
+----------------+----------------+----------------+----------------+

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

length: u32

Length of the netlink packet, including the header and the payload

message_type: u16

NetlinkMessage type. The meaning of this field depends on the netlink protocol family in use.

flags: u16

Flags. It should be set to one of the NLM_F_* constants.

sequence_number: u32

Sequence number of the packet

port_number: u32

Port number (usually set to the the process ID)

Trait Implementations

impl Clone for NetlinkHeader

fn clone(&self) -> NetlinkHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NetlinkHeader

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

Formats the value using the given formatter.

impl Default for NetlinkHeader

fn default() -> NetlinkHeader

Returns the “default value” for a type.

impl Emitable for NetlinkHeader

fn buffer_len(&self) -> usize

Return the length of the serialized data.

fn emit(&self, buffer: &mut [u8])

Serialize this types and write the serialized data into the given buffer.

impl Hash for NetlinkHeader

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a, T: AsRef<[u8]> + ?Sized> Parseable<NetlinkBuffer<&'a T>> for NetlinkHeader

fn parse(buf: &NetlinkBuffer<&'a T>) -> Result<NetlinkHeader, DecodeError>

Deserialize the current type.

impl PartialEq<NetlinkHeader> for NetlinkHeader

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