Struct Resource

#[non_exhaustive]
pub struct Resource {
    pub entity_type: String,
    pub uid: ResourceId,
    pub attrs: IndexMap<String, Value>,
}

A resource being acted on. The entity_type is the Cedar type name (Mailbox, Repository, etc) and uid is the entity’s ID.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

entity_type: String

uid: ResourceId

attrs: IndexMap<String, Value>

Implementations

impl Resource

pub fn new(entity_type: impl Into<String>, uid: impl Into<ResourceId>) -> Self

Construct a resource with no attributes.

pub fn with_attr(self, k: impl Into<String>, v: impl Into<Value>) -> Self

Add an attribute and return self for chaining.

pub fn entity_uid(&self) -> String

👎Deprecated since 0.2.1: Use the Display impl to write into an existing buffer (no allocation).

Full Cedar entity UID like Mailbox::"alice@acme".

Prefer the Display impl for formatting into an existing buffer (avoids a String allocation on the hot path). This method is retained for callers that genuinely need an owned String (e.g. serialization to JSON).

Trait Implementations

impl Clone for Resource

fn clone(&self) -> Resource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Resource

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Resource

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Resource

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

Formats the value using the given formatter.

impl PartialEq for Resource

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
