}Expand description
Condition in a policy definition. Represents the predicate logic for security rules.
Variants§
FieldEquals
Field comparison: the user's role equals "admin"
Fields
FieldBool
Boolean field: the user's verified equals true
Predicate
Predicate call: the user is admin
ObjectFieldEquals
Whole-subject vs object field: the user equals the document's owner
(the object field shares the subject’s type). Compiles to self == &object.field.
SubjectFieldEqualsObjectField
Cross-field comparison: the user's name equals the document's owner.
Compiles to self.<subject_field> == <object>.<object_field>.
Or(Box<PolicyCondition>, Box<PolicyCondition>)
Logical OR: A OR B
And(Box<PolicyCondition>, Box<PolicyCondition>)
Logical AND: A AND B

fn into_any(self: Box<T>) -> Box<dyn Any>
Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
