    fromResult?: (res?: Result) => Res

    fromResult allows you to provide a function to convert the generic Result type into another type

    Example: Convert a response to boolean

    Assuming that your policy evaluates to an object like {"allowed": true}, this fromResult function would let you convert it to a boolean:

    const res = await new OPAClient(serverURL).evaluate<any, boolean>(
      "policy/result",
      { action: "read" },
      {
        fromResult: (r?: Result) => (r as Record<string, any>)["allowed"] ?? false,
      },
    );
    rejectMixed?: boolean

    With rejectMixed set, a batch result that contains any errors causes a Promise rejection.

    retries?: RetryConfig

    Set or override a retry policy on HTTP calls.

    retryCodes?: string[]

    Specifies the status codes which should be retried using the given retry policy.

    serverURL?: string | URL

    Overrides the base server URL that will be used by an operation.

    timeoutMs?: number

    Sets a timeout, in milliseconds, on HTTP requests made by an SDK method. If fetchOptions.signal is set then it will take precedence over this option.
