Enum ConnectionState 

pub enum ConnectionState {
    Closed,
    SynSent,
    SynReceived,
    Established,
    FinWait,
    Closing,
    TimeWait,
}

Connection state for the constrained protocol

Variants

Closed

Connection is closed (initial or final state)

SynSent

SYN sent, waiting for SYN-ACK

SynReceived

SYN received, SYN-ACK sent, waiting for ACK

Established

Connection established, data can flow

FinWait

FIN sent, waiting for ACK

Closing

Received FIN, sent ACK, waiting to close

TimeWait

Waiting for enough time to pass before reusing connection ID

Implementations

impl ConnectionState

pub const fn can_send_data(&self) -> bool

Check if this state allows sending data

Check if this state allows receiving data

pub const fn is_open(&self) -> bool

Check if connection is considered open

pub const fn is_closed(&self) -> bool

Check if connection is closed or closing

pub const fn is_established(&self) -> bool

Check if connection is fully established

pub fn timeout(&self) -> Duration

Get timeout duration for this state

Returns how long to wait in this state before timing out.
