Struct Connection 

pub struct Connection { /* private fields */ }

Handle to a live FIX session.

Cloning is cheap; all clones refer to the same session. The session is closed when the transport drops, the counterparty logs out, a heartbeat timeout is detected, or Connection::logout completes.

Implementations

impl Connection

pub fn session_id(&self) -> &SessionId

Returns the session identifier.

pub async fn send(&self, message: OutboundMessage) -> Result<(), EngineError>

Sends an application message on the session.

The engine stamps the standard header (including MsgSeqNum) and trailer; the message only needs body fields.

Arguments

• message - The application message to send

Errors

Returns EngineError::Closed if the session is already closed.

pub async fn logout(&self) -> Result<(), EngineError>

Initiates a graceful logout.

A Logout message is sent to the counterparty; the session closes when the Logout acknowledgement arrives or the logout timeout elapses. Use Connection::wait_closed to observe completion.

Errors

Returns EngineError::Closed if the session is already closed.

pub async fn wait_closed(&self)

Waits until the session is closed.

Fires on transport drop, counterparty logout, heartbeat timeout, or completion of a locally initiated logout. Returns immediately if the session is already closed.

pub fn is_closed(&self) -> bool

Returns true if the session is closed.

pub fn is_timed_out(&self) -> bool

Returns true if the session has detected a heartbeat timeout (a TestRequest went unanswered for a full heartbeat interval).

pub fn next_sender_seq(&self) -> u64

Returns the next outgoing (sender) sequence number.

pub fn next_target_seq(&self) -> u64

Returns the next expected incoming (target) sequence number.
