Method SetUsable

internal/pool/conn.go:297–305

SetUsable sets the usable flag for the connection (lock-free). Deprecated: Use GetStateMachine().Transition() directly for better state management. This method is kept for backwards compatibility. This should be called to mark a connection as usable after initialization or to release it after a ba

(usable bool)

// Prefer CompareAndSwapUsable() when acquiring exclusive access to avoid race conditions.
// Deprecated: Use GetStateMachine().Transition() directly for better state management.
func (cn *Conn) SetUsable(usable bool) {
	if usable {
		// Transition to IDLE state (ready to be acquired)
		cn.stateMachine.Transition(StateIdle)
	} else {
		// Transition to UNUSABLE state (for background operations)
		cn.stateMachine.Transition(StateUnusable)
	}
}

// IsInited returns true if the connection has been initialized.
// This is a backward-compatible wrapper around the state machine.
