Module failsafe::backoff

Contains various backoff strategies.

Strategies are defined as Iterator<Item=Duration>.

Structs

EqualJittered

Creates infinite stream of backoffs that keep the exponential growth, and jitter between 0 and that amount.

Exponential

An infinite stream of backoffs that keep the exponential growth from start until it reaches max.

FullJittered

An infinite stream of backoffs that keep half of the exponential growth, and jitter between 0 and that amount.

ThreadLocalGenRange

Thread local random generator, invokes rand::thread_rng.

ThreadRng

A reference to the thread-local generator

Traits

GenRange

Random generator.

Functions

Type Definitions

Backoff
