pub struct CanCreate<Condition = ()>(pub Condition);
Expand description
The CanCreate
strategy represents the ability to create 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 create 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 created
under the given condition?”. For instance, “Can a specific user create an asset?”.
