As someone who typically GMs, I'm accustomed to seeing resistances specified in monster stat blocks as "resistant to bludgeoning, piercing and slashing damage from non-magical weapons".
However the barbarian class feature Rage states that a benefit of raging is "You have resistance to bludgeoning, piercing, and slashing damage," neglecting any mention of magical weapons.
Though PCs encountering magical weapons may be rare, are there any other rules which stipulate that the basic rage resistances don't apply towards magical weapons?

The exclusion of any mention of magical weapons isn't accidental, Barbarians are resistant to bludgeoning, piercing, and slashing damage whether it's magical or otherwise as it's key to their ability to have staying power on the front line. By comparison, the Heavy Armor Mastery feat makes the clear distinction for magic weapons, therefore, it's not unreasonable that the design intent is on purpose.
This is important because otherwise the Barbarian would experience a huge drop off in survivability as the game progressed passed a certain tier when a lot of enemies' weapons are being described as inherently magical.
