Enum EntityReference

#[non_exhaustive]
pub enum EntityReference {
    Identifier(EntityIdentifier),
    Unspecified(bool),
    Unknown,
}

Contains information about a principal or resource that can be referenced in a Cedar policy.

This data type is used as part of the PolicyFilter structure that is used as a request parameter for the ListPolicies operation..

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Identifier(EntityIdentifier)

The identifier of the entity. It can consist of either an EntityType and EntityId, a principal, or a resource.

Unspecified(bool)

Used to indicate that a principal or resource is not specified. This can be used to search for policies that are not associated with a specific principal or resource.

Unknown

The Unknown variant represents cases where new union variant was received. Consider upgrading the SDK to the latest available version. An unknown enum variant

Note: If you encounter this error, consider upgrading your SDK to the latest version. The Unknown variant represents cases where the server sent a value that wasn’t recognized by the client. This can happen when the server adds new functionality, but the client has not been updated. To investigate this, consider turning on debug logging to print the raw HTTP response.

Implementations

impl EntityReference

pub fn as_identifier(&self) -> Result<&EntityIdentifier, &Self>

Tries to convert the enum instance into Identifier, extracting the inner EntityIdentifier. Returns Err(&Self) if it can’t be converted.

pub fn is_identifier(&self) -> bool

Returns true if this is a Identifier.

pub fn as_unspecified(&self) -> Result<&bool, &Self>

Tries to convert the enum instance into Unspecified, extracting the inner bool. Returns Err(&Self) if it can’t be converted.

pub fn is_unspecified(&self) -> bool

Returns true if this is a Unspecified.

pub fn is_unknown(&self) -> bool

Returns true if the enum instance is the Unknown variant.

Trait Implementations

impl Clone for EntityReference

fn clone(&self) -> EntityReference

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EntityReference

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

Formats the value using the given formatter.

impl PartialEq for EntityReference

fn eq(&self, other: &EntityReference) -> 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.
