Struct cedar_policy::EntityUid

#[repr(transparent)]
pub struct EntityUid(_);

Unique Id for an entity, such as User::"alice"

Implementations

impl EntityUid

pub fn type_name(&self) -> &EntityTypeName

Returns the portion of the Euid that represents namespace and entity type

pub fn id(&self) -> &EntityId

Returns the id portion of the Euid

pub fn from_type_name_and_id(name: EntityTypeName, id: EntityId) -> Self

Creates EntityUid from EntityTypeName and EntityId

pub fn from_json(json: Value) -> Result<Self, impl Error>

Creates EntityUid from a JSON value, which should have either the implicit or explicit __entity form.

Examples:

• { "__entity": { "type": "User", "id": "123abc" } }
• { "type": "User", "id": "123abc" }

Trait Implementations

impl Clone for EntityUid

fn clone(&self) -> EntityUid

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EntityUid

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

Formats the value using the given formatter.

impl Display for EntityUid

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

Formats the value using the given formatter.

impl FromStr for EntityUid

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

This is deprecated (starting with Cedar 1.2); use EntityUid::from_type_name_and_id() or EntityUid::from_json() instead.

type Err = ParseErrors

The associated error which can be returned from parsing.

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,

Feeds a slice of this type into the given Hasher.

impl Ord for EntityUid

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<EntityUid> for EntityUid

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<EntityUid> 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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl RefCast for EntityUid

type From = EntityUID

fn ref_cast(_from: &Self::From) -> &Self

fn ref_cast_mut(_from: &mut Self::From) -> &mut Self

impl Eq for EntityUid

impl StructuralEq for EntityUid

impl StructuralPartialEq for EntityUid
