Struct Nlattr

pub struct Nlattr<T, P> {
    pub nla_len: u16,
    pub nla_type: AttrType<T>,
    pub nla_payload: P,
}

Struct representing netlink attributes and payloads

Fields

nla_len: u16

Length of the attribute header and payload together

nla_type: AttrType<T>

Type information for the netlink attribute

nla_payload: P

Payload of the attribute - either parsed or a binary buffer

Implementations

impl<T> Nlattr<T, Buffer>

where T: NlAttrType,

pub fn new<P>( nla_nested: bool, nla_network_order: bool, nla_type: T, nla_payload: P, ) -> Result<Self, SerError>

where P: Size + ToBytes,

Create a new Nlattr with parameters for setting bitflags in the header.

pub fn add_nested_attribute<TT, P>( &mut self, attr: &Nlattr<TT, P>, ) -> Result<(), SerError>

where TT: NlAttrType, P: ToBytes,

Add a nested attribute to the end of the payload.

pub fn get_attr_handle<R>( &self, ) -> Result<AttrHandle<'_, GenlBuffer<R, Buffer>, Nlattr<R, Buffer>>, DeError>

where R: NlAttrType,

Return an AttrHandle for attributes nested in the given attribute payload

pub fn get_attr_handle_mut<R>( &mut self, ) -> Result<AttrHandleMut<'_, GenlBuffer<R, Buffer>, Nlattr<R, Buffer>>, DeError>

where R: NlAttrType,

Return a mutable AttrHandle for attributes nested in the given attribute payload

Trait Implementations

impl<T> Attribute<T> for Nlattr<T, Buffer>

where T: NlAttrType,

fn payload(&self) -> &Buffer

Get the payload of the given attribute.

fn set_payload<P>(&mut self, payload: &P) -> Result<(), SerError>

where P: Size + ToBytes,

Set the payload to a data type that implements ToBytes - this function will overwrite the current payload.

fn get_payload_as<'a, R>(&'a self) -> Result<R, DeError>

where R: FromBytes<'a>,

Get an Nlattr payload as the provided type parameter, R.

fn get_payload_as_with_len<'a, R>(&'a self) -> Result<R, DeError>

where R: FromBytesWithInput<'a, Input = usize>,

Get an Nlattr payload as the provided type parameter, R.

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

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

Formats the value using the given formatter.

impl<'lifetime, T: NlAttrType, P: FromBytesWithInput<'lifetime, Input = usize>> FromBytes<'lifetime> for Nlattr<T, P>

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

Takes a byte buffer and returns the deserialized data structure.

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

Strip padding from a netlink message.

impl<T, P> FromIterator<Nlattr<T, P>> for GenlBuffer<T, P>

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

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

Creates a value from an iterator.

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

fn header_size() -> usize

Return the size in bytes of the data structure header.

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

fn eq(&self, other: &Nlattr<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 Nlattr<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 of the payload and align it to the required netlink byte alignment.

impl<T: NlAttrType, P: ToBytes> ToBytes for Nlattr<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.
