Functions

func New

func New(options ...Option) backoff.Strategy

New initializes exponential backoff.Strategy. It implements exponential backoff algorithm as defined in https://github.com/grpc/grpc/blob/master/doc/connection-backoff.md.

Types

type Option

type Option func(*strategy)

func WithBaseDelay

func WithBaseDelay(d time.Duration) Option

WithBaseDelay is the amount of time to wait before retrying after the first failure. Default is 1 second.

func WithFactor

func WithFactor(factor float64) Option

WithFactor is applied to the backoff after each retry. Default value is 1.6

func WithJitter

func WithJitter(jitter float64) Option

WithJitter provides a range to randomize backoff delays. Default value is 0.2

func WithMaxDelay

func WithMaxDelay(d time.Duration) Option

WithMaxDelay is the upper bound of backoff delay. Default is 180 seconds.
