Struct RegoPolicyClient 

pub struct RegoPolicyClient { /* private fields */ }

Evaluates Rego policies in-process.

Policies and data documents are loaded once through the builder; every evaluation clones the prepared engine, sets the input and evaluates the rule data.<path>. An undefined rule value yields JsonValue::Null (not applicable); a rule path that does not exist is an PolicyError::Engine error, which approval policies treat as a denial.

Implementations

impl RegoPolicyClient

pub fn builder() -> RegoPolicyClientBuilder

Starts building a client.

pub fn from_policy( name: impl Into<String>, source: impl Into<String>, ) -> Result<Self, PolicyError>

Creates a client from a single policy module.

Errors

Returns PolicyError::Engine when the policy does not parse.

pub fn packages(&self) -> &[String]

The data.<package> paths of the loaded policy modules.
