Struct cedar_policy_core::ast::ResourceConstraint

pub struct ResourceConstraint { /* private fields */ }

Template constraint on resource head variables

Implementations

impl ResourceConstraint

pub fn new(constraint: PrincipalOrResourceConstraint) -> Self

Construct from constraint

pub fn as_inner(&self) -> &PrincipalOrResourceConstraint

Get constraint as ref

pub fn into_inner(self) -> PrincipalOrResourceConstraint

Get constraint by value

pub fn as_expr(&self) -> Expr

Convert into an Expression. It will be a boolean valued expression.

pub fn any() -> Self

Unconstrained.

pub fn is_eq(euid: EntityUID) -> Self

Constrained to equal a specific euid.

pub fn is_eq_slot() -> Self

Constrained to equal a slot.

pub fn is_in_slot() -> Self

Constrained to be in a slot

pub fn is_in(euid: EntityUID) -> Self

Hierarchical constraint.

pub fn with_filled_slot(self, euid: Arc<EntityUID>) -> Self

Fill in the Slot, if any, with the given EUID

Trait Implementations

impl Clone for ResourceConstraint

fn clone(&self) -> ResourceConstraint

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ResourceConstraint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ResourceConstraint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ResourceConstraint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ResourceConstraint> for ResourceConstraint

fn from(constraint: ResourceConstraint) -> ResourceConstraint

Converts to this type from the input type.

impl Hash for ResourceConstraint

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ResourceConstraint

fn eq(&self, other: &ResourceConstraint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ResourceConstraint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<ResourceConstraint> for ResourceConstraint

type Error = EstToAstError

The type returned in the event of a conversion error.

fn try_from( constraint: ResourceConstraint, ) -> Result<ResourceConstraint, EstToAstError>

Performs the conversion.
