Variants

FieldEquals

Field comparison: the user's role equals "admin"

Fields

field: Symbol

value: Symbol

is_string_literal: bool

Whether the value came from a string literal (needs quotes in codegen)

FieldBool

Boolean field: the user's verified equals true

Fields

field: Symbol

value: bool

Predicate

Predicate call: the user is admin

Fields

subject: Symbol

predicate: Symbol

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.

Fields

subject: Symbol

object: Symbol

field: Symbol

SubjectFieldEqualsObjectField

Cross-field comparison: the user's name equals the document's owner. Compiles to self.<subject_field> == <object>.<object_field>.

Fields

subject_field: Symbol

object: Symbol

object_field: Symbol

Or(Box<PolicyCondition>, Box<PolicyCondition>)

Logical OR: A OR B

And(Box<PolicyCondition>, Box<PolicyCondition>)

Logical AND: A AND B
