Struct Policy

pub struct Policy { /* private fields */ }

Serde JSON structure for policies and templates in the EST format Note: Before attempting to build an est::Policy from a cst::Policy you must first ensure that the CST can be transformed into an AST. The CST-to-EST transformation does not duplicate all checks performed by the CST-to-AST transformation, so attempting to convert an invalid CST to an EST may succeed.

Implementations

impl Policy

pub fn link( self, vals: &HashMap<SlotId, EntityUidJson>, ) -> Result<Self, LinkingError>

Fill in any slots in the policy using the values in vals. Throws an error if vals doesn’t contain a necessary mapping, but does not throw an error if vals contains unused mappings – and in particular if self is an inline policy (in which case it is returned unchanged).

pub fn sub_entity_literals( self, mapping: &BTreeMap<EntityUID, EntityUID>, ) -> Result<Self, JsonDeserializationError>

Substitute entity literals

impl Policy

pub fn try_into_ast_policy( self, id: Option<PolicyID>, ) -> Result<Policy, FromJsonError>

Try to convert a Policy into a ast::Policy.

This process requires a policy ID. If not supplied, this method will fill it in as “JSON policy”.

pub fn try_into_ast_template( self, id: Option<PolicyID>, ) -> Result<Template, FromJsonError>

Try to convert a Policy into a ast::Template. Returns an error if the input is a static policy.

This process requires a policy ID. If not supplied, this method will fill it in as “JSON policy”.

pub fn try_into_ast_policy_or_template( self, id: Option<PolicyID>, ) -> Result<Template, FromJsonError>

Try to convert a Policy into a ast::Template. The Template may represent a template or static policy (which is a template with zero slots).

This process requires a policy ID. If not supplied, this method will fill it in as “JSON policy”.

Trait Implementations

impl Clone for Policy

fn clone(&self) -> Policy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Policy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Policy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Policy

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

Formats the value using the given formatter.

impl From<Policy> for Policy

Convert AST to EST

fn from(ast: Policy) -> Policy

Converts to this type from the input type.

impl From<Template> for Policy

Convert AST to EST

fn from(ast: Template) -> Policy

Converts to this type from the input type.

impl PartialEq for Policy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Policy> for Policy

type Error = ParseErrors

The type returned in the event of a conversion error.

fn try_from(policy: Policy) -> Result<Policy, ParseErrors>

Performs the conversion.
