Struct CanDestroy

pub struct CanDestroy<Condition = ()>(pub Condition);

The CanDestroy strategy represents the ability to destroy an asset. It is both an inspect and update strategy.

• As the inspect strategy, it returns bool.
• As the update strategy, it accepts bool.

By default, this strategy means the ability to destroy an asset “in general”. However, a user can define several variants of this strategy by supplying the Condition type. Using the Condition value, we are formulating the question, “Can this be destroyed under the given condition?”. For instance, “Can a specific user destroy an asset of another user?”.
