Struct RemainingBudget 

pub struct RemainingBudget {
    pub deadline: Option<Duration>,
    pub polls: Option<u32>,
    pub cost: Option<u64>,
}

A point-in-time snapshot of the remaining headroom in a Budget.

Produced by Budget::remaining. Every dimension uses None to mean “effectively unlimited” (no deadline configured, u32::MAX poll quota, or no cost quota), so callers never need to know the sentinel encodings.

The canonical use is adaptive control flow such as “do I have time for another retry?”:

let left = budget.remaining(now);
let can_retry = left.deadline.is_none_or(|d| d > estimated_attempt);

Fields

deadline: Option<Duration>

Time left until the deadline, or None if no deadline is set or the deadline has already passed with no remaining time (see Budget::remaining_time for the exact past-deadline semantics).

polls: Option<u32>

Polls left, or None if effectively unlimited.

cost: Option<u64>

Cost units left, or None if no cost quota is configured.
