Types

type Exponential

type Exponential struct {
	// Config contains all options to configure the backoff algorithm.
	Config grpcbackoff.Config
}

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

func (Exponential) Backoff

func (bc Exponential) Backoff(retries int) time.Duration

Backoff returns the amount of time to wait before the next retry given the number of retries.

type Strategy

type Strategy interface {
	// Backoff returns the amount of time to wait before the next retry given
	// the number of consecutive failures.
	Backoff(retries int) time.Duration
}

Strategy defines the methodology for backing off after a grpc connection failure.
