Enum SocketState 

enum SocketState {
    Initial,
    Bound(SocketAddr),
    Listening(TcpListener),
    Connecting(TcpStream),
    Connected(TcpStream),
}

Variants

Initial

No syscall after socket has been made.

Bound(SocketAddr)

The bind syscall has been called on the socket. This is only reachable from the SocketState::Initial state.

Listening(TcpListener)

The listen syscall has been called on the socket. This is only reachable from the SocketState::Bound state.

Connecting(TcpStream)

The connect syscall has been called and we weren’t yet able to ensure the connection is established. This is only reachable from the SocketState::Initial state.

Connected(TcpStream)

The connect syscall has been called on the socket and we ensured that the connection is established, or the socket was created by the accept syscall. For a socket created using the connect syscall, this is only reachable from the SocketState::Connecting state.

Implementations

impl SocketState

pub fn try_set_connected(&mut self) -> Result<(), SocketIoError>

If the socket is currently in SocketState::Connecting, try to ensure that the connection is established by first checking that [TcpStream::take_error] doesn’t return an error and then by checking that [TcpStream::peer_addr] returns the address of the connected peer.

If the connection is established or the socket is in any other state, Ok is returned.

Important: On Windows hosts this function can only be used to ensure a socket is connected after a [Interest::WRITABLE] event was received.

Trait Implementations

impl Debug for SocketState

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
