Struct nix::sys::socket::sockopt::TcpFastOpenConnect

pub struct TcpFastOpenConnect;

Enables TCP Fast Open (RFC 7413) on a connecting socket. If a fast open cookie is not available (first attempt to connect), connect syscall will behave as usual, except for internally trying to solicit a cookie from remote peer. When cookie is available, the next connect syscall will immediately succeed without actually establishing TCP connection. The connection establishment will be defered till the next write or sendmsg syscalls on the socket, allowing TCP prtocol to establish connection and send data in the same packets. Note: calling read right after connect without write on the socket will cause the blocking socket to be blocked forever.

Trait Implementations

impl Clone for TcpFastOpenConnect

fn clone(&self) -> TcpFastOpenConnect

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TcpFastOpenConnect

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

Formats the value using the given formatter.

impl GetSockOpt for TcpFastOpenConnect

type Val = bool

fn get<F: AsFd>(&self, fd: &F) -> Result<bool>

Look up the value of this socket option on the given socket.

impl Hash for TcpFastOpenConnect

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TcpFastOpenConnect

fn eq(&self, other: &TcpFastOpenConnect) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SetSockOpt for TcpFastOpenConnect

type Val = bool

fn set<F: AsFd>(&self, fd: &F, val: &bool) -> Result<()>

Set the value of this socket option on the given socket.
