Enum TcpSocketState

pub enum TcpSocketState {
    Closed,
    Listen,
    SynSent,
    SynReceived,
    Established,
    FinWait1,
    FinWait2,
    CloseWait,
    Closing,
    LastAck,
    TimeWait,
}

TCP socket state (simplified from smoltcp).

Used to communicate socket state from smoltcp to our state machine.

Variants

Closed

Socket is closed

Listen

Listening (server mode - not used here)

SynSent

SYN sent, waiting for SYN-ACK

SynReceived

SYN-ACK received, sending ACK

Established

Connection established

FinWait1

FIN sent, waiting for ACK

FinWait2

FIN-ACK received

CloseWait

Waiting for FIN from peer

Closing

FIN sent after CloseWait

LastAck

FIN received in FinWait1

TimeWait

Waiting for timeout

Implementations

impl TcpSocketState

pub fn is_active(self) -> bool

Check if socket is connected and can send/receive.

pub fn is_failed(self) -> bool

Check if connection attempt failed.

pub fn is_closing(self) -> bool

Check if connection is closing.

Trait Implementations

impl Clone for TcpSocketState

fn clone(&self) -> TcpSocketState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TcpSocketState

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

Formats the value using the given formatter.

impl PartialEq for TcpSocketState

fn eq(&self, other: &TcpSocketState) -> 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.
