pub fn rta_len(&self) -> &c_ushort

Length of the attribute

Source

pub fn rta_type(&self) -> &T

Type of the attribute

Source

pub fn rta_payload(&self) -> &P

Payload of the attribute

Source§

impl<T> Rtattr<T, Buffer>
where T: RtaType,

Source§

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

Source§

fn get_payload_as<R>(&self) -> Result<R, DeError>
where R: FromBytes,

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