Struct EvalState

Source

struct EvalState<'a> {
    ctx: &'a Context,
    request_json: OnceCell<Option<Value>>,
    response_json: OnceCell<Option<Value>>,
}

Expand description

Per-evaluation state: the context plus lazily-parsed JSON bodies, so a multi-rule expression parses each body at most once per eval.

Fields§

§ctx: &'a Context§request_json: OnceCell<Option<Value>>§response_json: OnceCell<Option<Value>>
