Enum cedar_policy_core::entities::TCComputation

pub enum TCComputation {
    AssumeAlreadyComputed,
    EnforceAlreadyComputed,
    ComputeNow,
}

Describes the option for how the TC (transitive closure) of the entity hierarchy is computed

Variants

AssumeAlreadyComputed

Assume that the TC has already been computed and that the input is a DAG before the call of Entities::from_entities.

EnforceAlreadyComputed

Enforce that the TC must have already been computed before the call of Entities::from_entities. If the given entities don’t include all transitive hierarchy relations, return an error. Also checks for cycles and returns an error if found.

ComputeNow

Compute the TC ourselves during the call of Entities::from_entities. This doesn’t make any assumptions about the input, which can in fact contain just parent edges and not transitive ancestor edges. Also checks for cycles and returns an error if found.

Trait Implementations

impl Clone for TCComputation

fn clone(&self) -> TCComputation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TCComputation

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

Formats the value using the given formatter.

impl Hash for TCComputation

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 PartialEq for TCComputation

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