Policy template datatype

Implementations§

source§

impl Template

source

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.

source

pub fn id(&self) -> &PolicyId

Get the PolicyId of this Template

source

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

Clone this Template with a new PolicyId

source

pub fn effect(&self) -> Effect

Get the Effect (Forbid or Permit) of this Template

source

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

Get an annotation value of this Template

source

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

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

source

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

Iterate over the open slots in this Template

source

pub fn principal_constraint(&self) -> TemplatePrincipalConstraint

Get the head constraint on this policy’s principal

source

pub fn action_constraint(&self) -> ActionConstraint

Get the head constraint on this policy’s action

source

pub fn resource_constraint(&self) -> TemplateResourceConstraint

Get the head constraint on this policy’s resource

impl PartialEq for Template

source§
