Struct AsyncPacketSocket 

pub struct AsyncPacketSocket { /* private fields */ }

An asynchronous socket wrapper for sending and receiving network packets.

This struct provides an async interface for working with raw sockets using the Tokio runtime.

Implementations

impl AsyncPacketSocket

pub async fn new(protocol: Protocol) -> Result<Self>

Creates a new async raw socket for the specified protocol.

Arguments

• protocol - The protocol to use (e.g., TCP, UDP)

pub async fn bind(&self, addr: Ipv4Addr) -> Result<()>

Binds the socket to a specific network interface.

Arguments

• addr - The IPv4 address to bind to

pub async fn send<P: PacketBuilder>( &self, packet: &P, dst_addr: Ipv4Addr, ) -> Result<usize, PacketError>

Sends a packet asynchronously to the specified destination.

Arguments

• packet - The packet to send
• dst_addr - The destination IPv4 address

Returns

• Ok(usize) - The number of bytes sent
• Err(PacketError) - If sending fails

pub async fn receive( &self, buffer: &mut [u8], ) -> Result<(usize, Ipv4Addr), PacketError>

Receives a packet asynchronously into the provided buffer.

Arguments

• buffer - The buffer to store the received packet

Returns

• Ok((usize, Ipv4Addr)) - The number of bytes received and source address
• Err(PacketError) - If receiving fails

pub async fn ready(&self, interest: Interest) -> Result<()>

Waits for the socket to become ready for the specified operation.

Arguments

• interest - The type of operation to wait for (read/write)
