Functions

func BeginningOfDay

func BeginningOfDay(days int) time.Time

func BeginningOfDayString

func BeginningOfDayString(days int, layout string) string

func EndOfDay

func EndOfDay(days int) time.Time

func EndOfDayString

func EndOfDayString(days int, layout string) string

func Now

func Now() time.Time

func NowString

func NowString(layout string) string

func TruncateToUTC

func TruncateToUTC(t time.Time, d time.Duration) time.Time

Truncate only happens in UTC semantics, apparently. observed values for truncating given time with 86400 secs:

before truncation: 2018/06/01 03:54:54 2018-06-01T03:18:00+09:00 after truncation: 2018/06/01 03:54:54 2018-05-31T09:00:00+09:00

This is really annoying when we want to truncate in local time so we hack: we take the apparent local time in the local zone, and pretend that it's in UTC. do our math, and put it back to the local zone

func TruncateToUTCString

func TruncateToUTCString(t time.Time, d time.Duration, layout string) string

Types

type EmptyExponentialBackOffOption

type EmptyExponentialBackOffOption struct{}

EmptyExponentialBackOffUrlOption does not alter the ExponentialBackOffuration. It can be embedded in another structure to build custom options.

This API is EXPERIMENTAL.

type ExponentialBackOff

type ExponentialBackOff struct {
	// contains filtered or unexported fields
}

func NewExponentialBackOff

func NewExponentialBackOff(opts ...ExponentialBackOffOption) *ExponentialBackOff

func (*ExponentialBackOff) ApplyOptions

func (o *ExponentialBackOff) ApplyOptions(options ...ExponentialBackOffOption) *ExponentialBackOff

func (*ExponentialBackOff) GetCurrentInterval

func (b *ExponentialBackOff) GetCurrentInterval() time.Duration

func (*ExponentialBackOff) GetElapsedTime

func (b *ExponentialBackOff) GetElapsedTime() time.Duration

func (*ExponentialBackOff) NextBackOff

func (b *ExponentialBackOff) NextBackOff() (time.Duration, bool)

false : have gone over the maximu elapsed time true : return remaining time

func (*ExponentialBackOff) Reset

func (b *ExponentialBackOff) Reset()
