Implementations§

Source§

impl UdpSocket

Source

pub fn send_to_blocking( &self, endpoint: SocketAddr, data: &[u8], ) -> Result<(), Error>

Send a packet to the given endpoint with the provided data.

Source

pub async fn send_to( &self, endpoint: SocketAddr, data: &[u8], ) -> Result<(), Error>

Send a packet to the given endpoint with the provided data.

Source

pub fn send_to_from_blocking( &self, endpoint: SocketAddr, local: IpAddr, data: &[u8], ) -> Result<(), Error>

Send a packet to endpoint, spoofing the source address as local.

Used by a forwarder so reply datagrams appear to originate from the original destination the peer expected.

Source

pub async fn send_to_from( &self, endpoint: SocketAddr, local: IpAddr, data: &[u8], ) -> Result<(), Error>

Send a packet to endpoint, spoofing the source address as local.

Used by a forwarder so reply datagrams appear to originate from the original destination the peer expected.

Source

pub fn recv_from_blocking( &self, buf: &mut [u8], ) -> Result<(SocketAddr, usize), Error>

Receive a packet into the given buffer.

Source

pub fn recv_from_bytes_blocking(&self) -> Result<(SocketAddr, Bytes), Error>

Receive a packet bytes buffer.

Source

pub async fn recv_from( &self, buf: &mut [u8], ) -> Result<(SocketAddr, usize), Error>

Receive a packet into the given buffer.

Source

pub async fn recv_from_bytes(&self) -> Result<(SocketAddr, Bytes), Error>

Asynchronously receive a packet bytes buffer.

Source

pub fn recv_from_with_dst_bytes_blocking( &self, ) -> Result<(SocketAddr, SocketAddr, Bytes), Error>

Receive a packet, also reporting the local (destination) address it was sent to.

Under any-IP acceptance the local address is the original packet destination – a forwarder needs it to know which real socket to relay through. Returns (remote, local, payload).

Source

pub async fn recv_from_with_dst_bytes( &self, ) -> Result<(SocketAddr, SocketAddr, Bytes), Error>

Receive a packet, also reporting the local (destination) address it was sent to.

Under any-IP acceptance the local address is the original packet destination – a forwarder needs it to know which real socket to relay through. Returns (remote, local, payload).

Source

pub const fn local_addr(&self) -> SocketAddr

Report the local endpoint to which this socket is bound.
