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

Growth example with factor = 2.0: 1 s → 2 s → 4 s → 8 s → … → 30 s (capped).

Also

• JitterPolicy jitter strategy applied to each delay.
• RestartPolicy controls when to restart; backoff controls delay.
• BackoffPolicy::validate parameter validation.

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<()>

Validate backoff parameters.

Checks:

• first_ms > 0
• max_ms >= first_ms
• factor >= 1.0 and finite

Trait Implementations

impl Clone for BackoffPolicy

fn clone(&self) -> BackoffPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 a sensible default: full jitter, 1s initial, 30s max, factor 2.

impl<'de> Deserialize<'de> for BackoffPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for BackoffPolicy

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BackoffPolicy

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BackoffPolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
