Struct capsules_extra::net::udp::udp_send::UDPSendStruct

pub struct UDPSendStruct<'a, T: IP6Sender<'a>> { /* private fields */ }

This is a specific instantiation of the UDPSender trait. Note that this struct contains a reference to an IP6Sender which it forwards packets to (and receives callbacks from).

Implementations

impl<'a, T: IP6Sender<'a>> UDPSendStruct<'a, T>

pub fn new( udp_mux_sender: &'a MuxUdpSender<'a, T>, udp_vis: &'static UdpVisibilityCapability, ) -> UDPSendStruct<'a, T>

Trait Implementations

impl<'a, T: IP6Sender<'a>> ListNode<'a, UDPSendStruct<'a, T>> for UDPSendStruct<'a, T>

fn next(&'a self) -> &'a ListLink<'a, UDPSendStruct<'a, T>>

impl<'a, T: IP6Sender<'a>> UDPSender<'a> for UDPSendStruct<'a, T>

Below is the implementation of the UDPSender traits for the UDPSendStruct.

fn set_client(&self, client: &'a dyn UDPSendClient)

This function sets the client for the UDPSender instance

fn send_to( &'a self, dest: IPAddr, dst_port: u16, buf: SubSliceMut<'static, u8>, net_cap: &'static NetworkCapability, ) -> Result<(), SubSliceMut<'static, u8>>

This function constructs a UDPHeader and sends the payload to the provided destination IP address and destination port from the src port contained in the UdpPortBindingTx.

fn driver_send_to( &'a self, dest: IPAddr, dst_port: u16, src_port: u16, buf: SubSliceMut<'static, u8>, _driver_send_cap: &dyn UdpDriverCapability, net_cap: &'static NetworkCapability, ) -> Result<(), SubSliceMut<'static, u8>>

This function is identical to send_to() except that it takes in an explicit src_port instead of a binding. This allows it to be used by the userspace driver, above which apps are bound to multiple ports

fn send( &'a self, dest: IPAddr, udp_header: UDPHeader, buf: SubSliceMut<'static, u8>, net_cap: &'static NetworkCapability, ) -> Result<(), SubSliceMut<'static, u8>>

This function constructs an IP packet from the completed UDPHeader and buffer, and sends it to the provided IP address

fn get_binding(&self) -> Option<UdpPortBindingTx>

fn is_bound(&self) -> bool

fn set_binding(&self, binding: UdpPortBindingTx) -> Option<UdpPortBindingTx>
