Method SetUsed

internal/pool/conn.go:368–374

SetUsed sets the used flag for the connection (lock-free). This should be called when returning a connection to the pool (set to false) or when a single-connection pool retrieves its connection (set to true). Prefer CompareAndSwapUsed() when acquiring from a multi-connection pool to avoid race con

(val bool)

// avoid race conditions.
// Deprecated: Use GetStateMachine().Transition() directly for better state management.
func (cn *Conn) SetUsed(val bool) {
	if val {
		cn.stateMachine.Transition(StateInUse)
	} else {
		cn.stateMachine.Transition(StateIdle)
	}
}

// getNetConn returns the current network connection using atomic load (lock-free).
// This is the fast path for accessing netConn without mutex overhead.
