Enum cedar_policy_core::ast::PrincipalOrResourceConstraint

pub enum PrincipalOrResourceConstraint {
    Any,
    In(EntityReference),
    Eq(EntityReference),
}

Represents the constraints for principals and resources. Can either not constrain, or constrain via == or in for a single entity literal.

Implementations

impl PrincipalOrResourceConstraint

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 as_expr(&self, v: PrincipalOrResource) -> Expr

Turn the constraint into an expr

arguments

• v - The variable name to be used in the expression.

pub fn display(&self, v: PrincipalOrResource) -> String

Pretty print the constraint

arguments

• v - The variable name to be used in the expression.

pub fn iter_euids(&self) -> impl Iterator<Item = &EntityUID>

Get an iterator over all of the entity uids in this constraint.

Trait Implementations

impl Clone for PrincipalOrResourceConstraint

fn clone(&self) -> PrincipalOrResourceConstraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PrincipalOrResourceConstraint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PrincipalOrResourceConstraint

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<PrincipalOrResourceConstraint> for PrincipalConstraint

fn from(constraint: PrincipalOrResourceConstraint) -> PrincipalConstraint

Converts to this type from the input type.

impl From<PrincipalOrResourceConstraint> for ResourceConstraint

fn from(constraint: PrincipalOrResourceConstraint) -> ResourceConstraint

Converts to this type from the input type.

impl Hash for PrincipalOrResourceConstraint

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 PrincipalOrResourceConstraint

fn eq(&self, other: &PrincipalOrResourceConstraint) -> 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 PrincipalOrResourceConstraint

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<PrincipalConstraint> for PrincipalOrResourceConstraint

type Error = EstToAstError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl TryFrom<ResourceConstraint> for PrincipalOrResourceConstraint

type Error = EstToAstError

The type returned in the event of a conversion error.

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

Performs the conversion.
