详细描述

Restricts one AttributeSetResourceAccount to Mana or Stamina.

This is a non-owning view, not another balance store and not another account identity. The wrapped AttributeSetResourceAccount remains the sole nonce issuer and reservation owner, so a credential produced by this view follows the same AccountNonce rules as a direct attribute account. The wrapped account must outlive the view; calls are synchronous on the wrapped account's owner thread.
