Struct BackoffSpec 

pub struct BackoffSpec {
    pub ratio: Option<f64>,
    pub min: Option<String>,
    pub max: Option<String>,
}

Retry-backoff settings carried by the map form of tries: (tries: {count: N, backoff: {ratio, min, max}}). Each field is optional — a missing key falls back to the op’s standalone retry_backoff* param, then the built-in default. Durations are kept as raw strings (e.g. "100ms", "10s") and parsed at wrap time by the runtime, so this crate needs no time parser.

Fields

ratio: Option<f64>

Geometric growth factor applied per retry: attempt k’s wait is min * ratio^(k-1), capped at max. 2.0 (the default) doubles; 1.0 holds the wait constant at min. None = default.

min: Option<String>

Backoff floor — the first retry’s wait (a duration string). None = default (100ms). "0" disables pacing entirely.

max: Option<String>

Backoff ceiling — the wait never exceeds this (a duration string). None = default (10s).
