Struct UdpTracker 

pub struct UdpTracker { /* private fields */ }

UDP tracker client (BEP 15).

Implementations

impl UdpTracker

pub fn new() -> Self

Creates a new UDP tracker client with default settings.

pub fn with_timeout(self, timeout: Duration) -> Self

Sets the timeout duration for UDP tracker requests.

pub fn with_dscp(self, dscp: u8) -> Self

Sets the DSCP/ToS value for outbound UDP packets.

pub fn build_connect_request(transaction_id: u32) -> [u8; 16]

Build a UDP connect request packet (BEP 15).

pub fn parse_connect_response( data: &[u8], expected_transaction_id: u32, ) -> Result<u64>

Parse a UDP connect response, returning the connection_id.

pub fn build_announce_request( connection_id: u64, transaction_id: u32, req: &AnnounceRequest, ) -> Vec<u8>

Build a UDP announce request packet (BEP 15).

pub fn parse_announce_response( data: &[u8], expected_transaction_id: u32, ) -> Result<UdpAnnounceResponse>

Parse a UDP announce response.

pub fn parse_announce_response_v6( data: &[u8], expected_transaction_id: u32, ) -> Result<UdpAnnounceResponse>

Parse a UDP announce response where the tracker address is IPv6.

Per BEP 15, the compact peer format matches the address family of the tracker endpoint: 18-byte entries (16 IP + 2 port) for IPv6 trackers.

pub async fn announce( &self, tracker_addr: &str, req: &AnnounceRequest, ) -> Result<UdpAnnounceResponse>

Perform a full UDP announce (connect + announce).

pub fn build_scrape_request( connection_id: u64, transaction_id: u32, info_hashes: &[Id20], ) -> Vec<u8>

Build a UDP scrape request packet (BEP 15).

Format: connection_id(8) + action(4, value=2) + transaction_id(4) + info_hash(20)*N

pub fn parse_scrape_response( data: &[u8], expected_transaction_id: u32, ) -> Result<UdpScrapeResponse>

Parse a UDP scrape response.

Format: action(4) + transaction_id(4) + [seeders(4) + completed(4) + leechers(4)]*N

pub async fn scrape( &self, tracker_addr: &str, info_hashes: &[Id20], ) -> Result<UdpScrapeResponse>

Perform a full UDP scrape (connect + scrape).
