Enum cedar_policy_core::est::ResourceConstraint

pub enum ResourceConstraint {
    All,
    Eq(EqConstraint),
    In(PrincipalOrResourceInConstraint),
}

Serde JSON structure for a resource head constraint in the EST format

Variants

All

No constraint (e.g., resource,)

Eq(EqConstraint)

== constraint

In(PrincipalOrResourceInConstraint)

in constraint

Implementations

impl ResourceConstraint

pub fn instantiate( self, vals: &HashMap<SlotId, EntityUidJSON>, ) -> Result<Self, InstantiationError>

Fill in any slots in the resource constraint using the values in vals. Throws an error if vals doesn’t contain a necessary mapping, but does not throw an error if vals contains unused mappings.

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 From<PrincipalOrResourceConstraint> for ResourceConstraint

fn from(constraint: PrincipalOrResourceConstraint) -> ResourceConstraint

Converts to this type from the input type.

impl From<ResourceConstraint> for ResourceConstraint

fn from(constraint: ResourceConstraint) -> ResourceConstraint

Converts to this type from the input type.

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 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.

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.
