Method Release

internal/pool/conn.go:828–831

Release releases the connection back to the pool. This is an optimized inline method for the hot path (Put operation). It tries to transition from IN_USE -> IDLE. Returns true if the connection was successfully released, false otherwise. Performance: This is faster than calling GetStateMachine() +

()

// If the state machine ever needs to notify waiters
// on this transition, update this to use TryTransitionFast().
func (cn *Conn) Release() bool {
	// Inline the hot path - single CAS operation
	return cn.stateMachine.state.CompareAndSwap(uint32(StateInUse), uint32(StateIdle))
}

// ClearHandoffState clears the handoff state after successful handoff.
// Makes the connection usable again.
