Struct LiteralPolicy

pub struct LiteralPolicy { /* private fields */ }

Represents either a static policy or a template linked policy.

Contains less rich information than Policy. In particular, this form is easier to convert to/from the Protobuf representation of a Policy, because it simply refers to the Template by its Id and does not contain a reference to the Template itself.

Implementations

impl LiteralPolicy

pub fn static_policy(template_id: PolicyID) -> Self

Create a LiteralPolicy representing a static policy with the given ID.

The policy set should also contain a (zero-slot) Template with the given ID.

pub fn template_linked_policy( template_id: PolicyID, link_id: PolicyID, values: SlotEnv, ) -> Self

Create a LiteralPolicy representing a template-linked policy.

The policy set should also contain the associated Template.

pub fn value(&self, slot: &SlotId) -> Option<&EntityUID>

Get the EntityUID associated with the given SlotId, if it exists

impl LiteralPolicy

pub fn reify( self, templates: &HashMap<PolicyID, Arc<Template>>, ) -> Result<Policy, ReificationError>

Attempt to reify this template linked policy. Ensures the linked template actually exists, replaces the id with a reference to the underlying template. Fails if the template does not exist. Consumes the policy.

pub fn get(&self, id: &SlotId) -> Option<&EntityUID>

Lookup the euid bound by a SlotId

pub fn id(&self) -> &PolicyID

Get the PolicyID of this static or template-linked policy.

pub fn template_id(&self) -> &PolicyID

Get the PolicyID of the template associated with this policy.

For static policies, this is just the static policy ID.

pub fn is_static(&self) -> bool

Is this a static policy

Trait Implementations

impl Clone for LiteralPolicy

fn clone(&self) -> LiteralPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LiteralPolicy

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

Formats the value using the given formatter.

impl Display for LiteralPolicy

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

Formats the value using the given formatter.

impl From<Policy> for LiteralPolicy

fn from(p: Policy) -> Self

Converts to this type from the input type.

impl Hash for LiteralPolicy

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 LiteralPolicy

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