Functions ¶

func Invoke ¶

func Invoke(ctx context.Context, stub APICall, opts ...CallOption) error

Invoke calls stub with a child of context modified by the specified options.

Types ¶

type APICall ¶

type APICall func(context.Context) error

A user defined call stub.

type BackoffSettings ¶

type BackoffSettings struct {
	DelayTimeoutSettings MultipliableDuration
	RPCTimeoutSettings   MultipliableDuration
}

Parameters to the exponential backoff algorithm for retrying.

type CallOption ¶

type CallOption interface {
	Resolve(*CallSettings)
}

func WithDelayTimeoutSettings ¶

func WithDelayTimeoutSettings(initial time.Duration, max time.Duration, multiplier float64) CallOption

WithDelayTimeoutSettings specifies:

• The initial delay time, in milliseconds, between the completion of the first failed request and the initiation of the first retrying request.
• The multiplier by which to increase the delay time between the completion of failed requests, and the initiation of the subsequent retrying request.
• The maximum delay time, in milliseconds, between requests. When this value is reached, `RetryDelayMultiplier` will no longer be used to increase delay time.

func WithRetryCodes ¶

func WithRetryCodes(retryCodes []codes.Code) CallOption

WithRetryCodes sets a list of Google API canonical error codes upon which a retry should be attempted.

type CallSettings ¶

type CallSettings struct {
	Timeout       time.Duration
	RetrySettings RetrySettings
}

Encapsulates the call settings for a particular API call.

func (CallSettings) Resolve ¶

func (w CallSettings) Resolve(s *CallSettings)

type MultipliableDuration ¶

type MultipliableDuration struct {
	Initial    time.Duration
	Max        time.Duration
	Multiplier float64
}

type RetrySettings ¶

type RetrySettings struct {
	RetryCodes      map[codes.Code]bool
	BackoffSettings BackoffSettings
}

Per-call configurable settings for retrying upon transient failure.
