Struct Puncher 

pub struct Puncher { /* private fields */ }

NAT traversal puncher for establishing direct connections.

The Puncher handles NAT type detection and hole punching to establish direct peer-to-peer connections.

Examples

// Get NAT information
let nat_info = puncher.nat_info();
println!("NAT Type: {:?}", nat_info.nat_type);

Implementations

impl Puncher

pub async fn punch(&self, punch_info: PunchInfo) -> Result<()>

Attempts to punch through NAT to reach a peer.

This method performs UDP hole punching to establish a direct connection with a peer behind NAT.

Arguments

• punch_info - Information about the target peer for punching

Examples

let punch_info = PunchInfo::default();
puncher.punch(punch_info).await?;

pub async fn punch_conv( &self, kcp_conv: u32, punch_info: PunchInfo, ) -> Result<()>

Attempts to punch through NAT with a custom KCP conversation ID.

This allows you to establish multiple independent KCP connections with different conversation IDs.

Arguments

• kcp_conv - The KCP conversation ID to use
• punch_info - Information about the target peer

Examples

let kcp_conv = 12345;
let punch_info = PunchInfo::default();
puncher.punch_conv(kcp_conv, punch_info).await?;

pub fn nat_info(&self) -> NatInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
