Struct FlexPollPolicy 

pub struct FlexPollPolicy {
    pub initial_delay: Duration,
    pub interval: Duration,
    pub max_attempts: u32,
}

Poll timing for the GetStatement stage of IbkrFlexClient::fetch_statement_xml.

The Flex Web Service generates statements asynchronously, so a fetch polls GetStatement until the statement is ready. This policy controls that polling:

• initial_delay — waited once before the first poll. The statement is created asynchronously, so the first GetStatement almost always reports 1019 (“still generating”); an initial delay keeps that near-certain miss from consuming one of the bounded attempts.
• interval — waited between subsequent polls.
• max_attempts — the number of GetStatement polls before giving up with IbkrFlexError::PollTimeout.

The Default budget (initial_delay 5 s, interval 5 s, max_attempts 12) suits a typical small activity statement. A caller fetching a large statement — which takes longer to generate — can widen the budget via IbkrFlexClient::with_poll_policy. A max_attempts of 0 yields an immediate IbkrFlexError::PollTimeout (an observable “no polling requested” outcome).

Fields

initial_delay: Duration

Delay before the first GetStatement poll.

interval: Duration

Delay between subsequent GetStatement polls.

max_attempts: u32

Maximum number of GetStatement poll attempts before IbkrFlexError::PollTimeout.
