Struct Capabilities 

pub struct Capabilities {
    pub gso: bool,
    pub gro: bool,
    pub sendmmsg: bool,
    pub ecn: bool,
    pub max_batch: usize,
}

Runtime-detected UDP optimization capabilities of a FastUdpSocket.

All fields are determined at build() time by probing the kernel and applying any kill-switches from FastUdpSocketBuilder. Call FastUdpSocket::capabilities to inspect what the socket is using.

Fields

gso: bool

Generic Segmentation Offload — send N packets via one sendmsg with UDP_SEGMENT. Linux only.

gro: bool

Generic Receive Offload — receive coalesced datagrams via recvmsg with UDP_GRO. Linux only.

sendmmsg: bool

sendmmsg batch send — multiple UDP datagrams in a single syscall. Linux (and some other Unix) only.

ecn: bool

Explicit Congestion Notification — send/receive IP TOS/TCLASS ancillary data.

max_batch: usize

Maximum number of datagrams the socket will attempt in a single batch call.

Implementations

impl Capabilities

pub fn none() -> Self

No optimizations — portable single-datagram fallback on every path.

Trait Implementations

impl Clone for Capabilities

fn clone(&self) -> Capabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Capabilities

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
