Struct neli::genl::Genlmsghdr

pub struct Genlmsghdr<C, T, H = NoUserHeader> {
    pub cmd: C,
    pub version: u8,
    pub header: H,
    /* private fields */
}

Struct representing generic netlink header and payload

Fields

cmd: C

Generic netlink message command

version: u8

Version of generic netlink family protocol

header: H

User specific header to send with netlink packet; defaults to an empty type to maintain backwards compatibility

Implementations

impl<C, T> Genlmsghdr<C, T>where
    C: Cmd,
    T: NlAttrType,

pub fn new(cmd: C, version: u8, attrs: GenlBuffer<T, Buffer>) -> Self

Create new generic netlink packet

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

Get handle for attribute parsing and traversal

pub fn get_attr_handle_mut(
    &mut self
) -> AttrHandleMut<'_, GenlBuffer<T, Buffer>, Nlattr<T, Buffer>>

Get handle for attribute mutable and traversal

impl<C, T, H> Genlmsghdr<C, T, H>

pub fn new_with_user_header(
    cmd: C,
    version: u8,
    header: H,
    attrs: GenlBuffer<T, Buffer>
) -> Self

Create a new netlink struct with a user header

Trait Implementations

impl<C: Debug, T: Debug, H: Debug> Debug for Genlmsghdr<C, T, H>

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

Formats the value using the given formatter.

impl<'lifetime, C: Cmd + TypeSize, T: NlAttrType, H: TypeSize + FromBytes<'lifetime>> FromBytesWithInput<'lifetime> for Genlmsghdr<C, T, H>

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<C: TypeSize, T, H: TypeSize> Header for Genlmsghdr<C, T, H>

fn header_size() -> usize

Return the size in bytes of the data structure header.

impl<C: PartialEq, T: PartialEq, H: PartialEq> PartialEq<Genlmsghdr<C, T, H>> for Genlmsghdr<C, T, H>

fn eq(&self, other: &Genlmsghdr<C, T, H>) -> 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.

impl<C: Size, T: Size, H: Size> Size for Genlmsghdr<C, T, H>

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<C: Cmd, T: NlAttrType, H: ToBytes> ToBytes for Genlmsghdr<C, T, H>

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.
