Grants this reward over Memberships and returns the ones it handed to OnGrant: asks CanGrant, keeps the memberships CanReceive accepts, collapses duplicates and hands that set to OnGrant.
A CanGrant refusal is the only error: nothing is delivered and the guard's own errors come back.

Attributes, Specifiers, and Effects
Specifiers
The following specifiers determine how you can interact with Grant in your programs. For the complete list of specifiers, see the Specifiers Page.
| Specifier | Meaning |
|---|---|
public |
The identifier is universally accessible. You can use this on modules, classes, interfaces, structs, enums, methods, and data. |
native |
Indicates that the definition details of the element are implemented in C++. Verse definitions with the native specifier auto-generate C++ definitions that a developer can then fill out its implementation. You can use this specifier on classes, interfaces, enums, methods, and data. |
final |
You can only use the final specifier on classes and members of classes. When a class has the final specifier, you cannot create a subclass of the class. When a field has the final specifier, you cannot override the field in a subclass. When a method has the final specifier, you cannot override the method in a subclass. |
Effects
The following effects determine how Grant behaves in your programs. For the complete list of effects, see the Effect Specifers section of the Specifiers Page.
| Effect | Meaning |
|---|---|
transacts |
This effect indicates that any actions performed by the function can be rolled back. The transacts effect is required any time a mutable variable (var) is written. You’ll be notified when you compile your code if the transacts effect was added to a function that can’t be rolled back. Note that this check is not done for functions with the native specifier. |
