Struct UdpOptions 

pub struct UdpOptions { /* private fields */ }

Available on crate feature udp only.

Options for UdpSocket::bind_with.

use net_io::{UdpBudget, UdpOptions};
let options = UdpOptions::new()
    .amplification_factor(3) // a QUIC handshake (RFC 9000)
    .global_budget(UdpBudget { datagrams_per_sec: 50_000, bytes_per_sec: 60_000_000, burst: 5_000 });

Implementations

impl UdpOptions

pub fn new() -> UdpOptions

Factor 1, a 10 s window, UdpBudget::SOURCE_DEFAULT per source, no global budget, 65,536 sources, IPv6-only for IPv6 addresses.

pub fn amplification_factor(self, factor: u8) -> UdpOptions

How many times the bytes received from an unverified source may be sent back to it (1 by default, at most 3; decision D-034).

pub fn amplification_window(self, window: Duration) -> UdpOptions

How long received bytes count toward a source’s send allowance (10 s by default, at least 1 s). The allowance spans the current and the previous window, so a reply just after a window boundary is not refused.

pub fn source_budget(self, budget: UdpBudget) -> UdpOptions

The budget of each source address.

pub fn global_budget(self, budget: UdpBudget) -> UdpOptions

A budget for the whole socket (none by default).

pub fn source_table(self, entries: u32) -> UdpOptions

How many sources are tracked (65,536 by default, about 130 bytes each).

pub fn packet_info(self, on: bool) -> UdpOptions

IPV6_V6ONLY for an IPv6 address (on by default). Off, an IPv6 socket also receives IPv4; sources are reported as IPv4 and replies to them work. Reports each datagram’s destination address in Datagram::destination, for a socket bound to a wildcard that must answer from the address it was asked on. One recvmsg per datagram instead of recvfrom. Unix only: bind_with fails with Unsupported on Windows, and recv_batch does not fill it.

pub fn ipv6_only(self, on: bool) -> UdpOptions

IPV6_V6ONLY for IPv6 addresses (on by default).
