Trait PolicyClient 

pub trait PolicyClient:
    Send
    + Sync
    + 'static {
    // Required method
    fn evaluate<'a>(
        &'a self,
        path: &'a str,
        input: JsonValue,
    ) -> BoxFuture<'a, Result<JsonValue, PolicyError>>;
}

Evaluates policies: a path and a JSON input in, a raw decision document out.

The raw document is normalized by PolicyDecision::normalize (approval) or parse_allowlist (capabilities). Clients return JsonValue::Null when the policy produced no value (an undefined rule), never an error.

Required Methods

fn evaluate<'a>( &'a self, path: &'a str, input: JsonValue, ) -> BoxFuture<'a, Result<JsonValue, PolicyError>>

Evaluates the policy at path with input.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
