Struct cedar_policy_core::ast::EntityUID

pub struct EntityUID { /* private fields */ }

Split into the EntityType representing the entity type, and the Eid representing its name

pub fn from_components(name: Name, eid: Eid) -> Self

Create a nominally-typed EntityUID with the given typename and EID

pub fn unspecified_from_eid(eid: Eid) -> Self

Create an unspecified EntityUID with the given EID

pub fn entity_type(&self) -> &EntityType

Get the type component.

pub fn eid(&self) -> &Eid

Convert an EntityUID to EntityUidJSON, using the ExplicitEntityEscape option

fn from(uid: &EntityUID) -> EntityUidJSON

Converts to this type from the input type.

impl From<&EntityUID> for TypeAndId

fn from(euid: &EntityUID) -> TypeAndId

Converts to this type from the input type.

impl From<EntityUID> for EntityReference

fn from(euid: EntityUID) -> Self

Converts to this type from the input type.

impl From<EntityUID> for EntityUidJSON

Convert an EntityUID to EntityUidJSON, using the ExplicitEntityEscape option

impl FromNormalizedStr for EntityUID

fn describe_self() -> &'static str

Short string description of the Self type, to be used in error messages. What are we trying to parse?

fn from_normalized_str(s: &str) -> Result<Self, ParseErrors>

Create a Self by parsing a string, which is required to be normalized. That is, the input is required to roundtrip with the Display impl on Self: Self::from_normalized_str(x).to_string() == x must hold.

impl FromStr for EntityUID

type Err = ParseErrors

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for EntityUID

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,

impl Ord for EntityUID

fn cmp(&self, other: &EntityUID) -> Ordering

This method returns an Ordering between self and other.

where Self: Sized,

Compares and returns the maximum of two values.

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for EntityUID

fn eq(&self, other: &EntityUID) -> 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 PartialOrd for EntityUID

fn partial_cmp(&self, other: &EntityUID) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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