Enum Jitter 

pub enum Jitter {
    None,
    Full,
    Equal,
}

Available on crate features async or sync only.

Jitter strategy applied to the computed backoff.

Reduces the risk that a thundering herd of clients all retry at the exact same moment. See AWS’s “Exponential backoff and jitter” post for the underlying math.

Variants

None

No jitter; sleep for exactly the computed exponential backoff.

Full

Sleep for a random duration in [0, backoff]. Maximum smoothing.

Equal

Sleep for a random duration in [backoff/2, backoff]. Compromise between predictability and herd-avoidance.

Implementations

impl Jitter

pub fn apply(self, value: Duration) -> Duration

Apply this jitter strategy to a deterministic backoff value.

Trait Implementations

impl Clone for Jitter

fn clone(&self) -> Jitter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Jitter

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

Formats the value using the given formatter.

impl Default for Jitter

fn default() -> Jitter

Returns the “default value” for a type.

impl PartialEq for Jitter

fn eq(&self, other: &Jitter) -> 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 Copy for Jitter

impl Eq for Jitter

impl StructuralPartialEq for Jitter
