Struct LogonEvent 

pub struct LogonEvent<'a> { /* private fields */ }

Logon event - received when a Logon message arrives from the counterparty

This event is only valid within the callback scope. It contains:

• Incoming logon message (read-only)
• Outgoing logon/logout messages (for acceptor only, mutable)
• Logon action (mutable) - determines how to respond

Lifetime

The lifetime 'a ensures this event cannot outlive the callback scope. All message references are zero-copy borrows from C++.

Implementations

impl<'a> LogonEvent<'a>

pub fn incoming_logon_message(&self) -> Option<&'a FixMessage>

Get the incoming logon message (read-only)

This is the Logon message received from the counterparty.

Returns

• Some(&FixMessage) - The incoming logon message
• None - Should never happen (logon events always have a message)

pub fn outgoing_logon_message(&mut self) -> Option<&'a mut FixMessage>

Get the outgoing logon message (for acceptor only)

This message is used when logon_action() is set to AcceptWithConfirmLogon. The acceptor can modify this message before it’s sent.

Returns

• Some(&mut FixMessage) - Mutable reference for acceptor to modify
• None - For initiators or if not available

pub fn outgoing_logout_message(&mut self) -> Option<&'a mut FixMessage>

Get the outgoing logout message (for acceptor only)

This message is used when logon_action() is set to DisconnectWithLogout. The acceptor can modify this message before it’s sent.

Returns

• Some(&mut FixMessage) - Mutable reference for acceptor to modify
• None - For initiators or if not available

pub fn logon_action(&self) -> LogonAction

Get the current logon action

Defaults to logon_action::ACCEPT_WITH_CONFIRM_LOGON.

Returns

One of the logon_action::* constants

pub fn set_logon_action(&mut self, action: LogonAction)

Set the logon action to control the response

Arguments

• action - How to respond to the logon:
  • logon_action::ACCEPT_WITH_CONFIRM_LOGON - Accept and send Logon response
  • logon_action::DISCONNECT_WITH_LOGOUT - Reject and send Logout message
  • logon_action::DISCONNECT - Reject without sending a message
