Struct cedar_policy :: Template Copy item path

impl Template

pub fn parse( id: Option<String>, src: impl AsRef<str> ) -> Result<Self, ParseErrors>

Attempt to parse a Template from source. If id is Some, then the resulting template will have that id. If the id is None, the parser will use the default “policy0”. The behavior around None may change in the future.

pub fn id(&self) -> &PolicyId

Get the PolicyId of this Template

pub fn new_id(&self, id: PolicyId) -> Self

Clone this Template with a new PolicyId

pub fn effect(&self) -> Effect

Get the Effect (Forbid or Permit) of this Template

pub fn annotation(&self, key: impl AsRef<str>) -> Option<&str>

Get an annotation value of this Template

pub fn annotations(&self) -> impl Iterator<Item = (&str, &str)>

Iterate through annotation data of this Template as key-value pairs

pub fn slots(&self) -> impl Iterator<Item = &SlotId>

Iterate over the open slots in this Template

pub fn principal_constraint(&self) -> TemplatePrincipalConstraint

Get the head constraint on this policy’s principal

pub fn action_constraint(&self) -> ActionConstraint

Get the head constraint on this policy’s action

pub fn resource_constraint(&self) -> TemplateResourceConstraint

Get the head constraint on this policy’s resource

pub fn from_json( id: Option<PolicyId>, json: Value ) -> Result<Self, FromJsonError>

Create a Template from its JSON representation. If id is Some, the policy will be given that Policy Id. If id is None, then “JSON policy” will be used. The behavior around None may change in the future.

pub fn to_json(&self) -> Result<Value, impl Diagnostic>

Get the JSON representation of this Template.
