Struct BackoffPolicy 

pub struct BackoffPolicy {
    pub jitter: JitterPolicy,
    pub first_ms: u64,
    pub max_ms: u64,
    pub factor: f64,
}

Exponential backoff configuration for task restart delays.

Field	Type	Default	Description
jitter	JitterPolicy	Full	Randomness applied to each delay
first_ms	u64	1_000	Initial delay (ms)
max_ms	u64	30_000	Maximum delay cap (ms)
factor	f64	2.0	Exponential growth multiplier

Before jitter, factor 2.0 grows 1s, 2s, 4s, 8s. Growth stops at max_ms.

Example

use solti_model::{BackoffPolicy, JitterPolicy};

let backoff = BackoffPolicy {
    jitter: JitterPolicy::Equal,
    first_ms: 1_000,
    max_ms: 30_000,
    factor: 2.0,
};

backoff.validate().unwrap();

Fields

jitter: JitterPolicy

Jitter policy applied to each computed delay.

first_ms: u64

Initial delay (ms) for exponential backoff.

max_ms: u64

Maximum allowed delay (ms).

factor: f64

Exponential growth multiplier.

Implementations

impl BackoffPolicy

pub fn validate(&self) -> ModelResult<()>

Validates backoff parameters.

Errors

Returns ModelError::Invalid when first_ms is zero, max_ms is below first_ms, or factor is not finite or below 1.0.

Example

use solti_model::BackoffPolicy;

let mut backoff = BackoffPolicy::default();
backoff.first_ms = 0;

assert!(backoff.validate().is_err());

Trait Implementations

impl Clone for BackoffPolicy

fn clone(&self) -> BackoffPolicy

Returns a duplicate of the value.

impl Debug for BackoffPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BackoffPolicy

fn default() -> Self

Returns full jitter, a 1-second initial delay, a 30-second cap, and factor 2.0.
