Struct Policy 

pub struct Policy { /* private fields */ }

The complete policy one surface is lowered under: the evaluation family it belongs to, which owner facts map to which claims, and what each claim permits.

Implementations

impl Policy

pub fn declared( family: Name, mappings: Vec<FactMapping>, permissions: Vec<Permission>, ) -> Result<Self, DeclarationError>

Declare the complete policy one surface is lowered under.

Errors

Returns DeclarationError::Doubled where one owner fact is mapped twice or two permissions name one claim, and DeclarationError::Unbounded where either roster outgrows its declared magnitude.

pub const fn family(&self) -> &Name

The evaluation family the rendered surface belongs to.

pub fn mappings(&self) -> &[FactMapping]

The owner-fact mappings, in the order they were declared.

pub fn permissions(&self) -> &[Permission]

The permissions, in the order they were declared.

pub fn claim_for(&self, fact: &Name) -> Option<&Name>

The claim mapped to one owner fact, where the policy maps it.
