Struct HttpPolicyClient 

pub struct HttpPolicyClient { /* private fields */ }

Evaluates policies through a policy server implementing the OPA REST Data API: POST <base>/v1/data/<path> with {"input": ..}, answering {"result": ..}.

A missing result (an undefined rule) yields JsonValue::Null. The server URL is validated with the configured UrlPolicy on every call; the default policy requires HTTPS and a public host, so a local sidecar needs UrlPolicy::new().allow_http().allow_private_networks().

Implementations

pub fn builder(base_url: Url) -> HttpPolicyClientBuilder

pub fn new(base_url: Url) -> Result<Self, PolicyError>

Creates a client with the default transport and URL policy.

Errors

Returns PolicyError::Transport when the default transport cannot be created.

pub fn base_url(&self) -> &Url

The server URL.
