Types

type Duration

type Duration interface {
	Add(t time.Time) time.Time
	Sub(t time.Time) time.Time
	EstimateNative() (time.Duration, bool)
}

func ParseISO8601

func ParseISO8601(from string) (Duration, error)

ParseISO8601 parses an ISO8601 duration as well as some Rill-specific extensions. (Section 3.7 of the standard supposedly allows extensions that do not interfere with the standard.) Current extensions are, 1. "inf" for representing an unbounded duration of time 2. X-To-Date and Previous-X duration supports with a prefix of "rill-" to DAX notations. Pulled from https://www.daxpatterns.com/standard-time-related-calculations/

type InfDuration added in v0.37.0

type InfDuration struct{}

func (InfDuration) Add added in v0.37.0

func (d InfDuration) Add(t time.Time) time.Time

func (InfDuration) EstimateNative added in v0.41.0

func (d InfDuration) EstimateNative() (time.Duration, bool)

func (InfDuration) Sub added in v0.37.0

func (d InfDuration) Sub(t time.Time) time.Time

type StandardDuration added in v0.37.0

type StandardDuration struct {
	Year   int
	Month  int
	Week   int
	Day    int
	Hour   int
	Minute int
	Second int
	// contains filtered or unexported fields
}

StandardDuration represents an ISO8601 duration with Rill-specific extensions. See ParseISO8601 for details.

func (StandardDuration) Add added in v0.37.0

func (d StandardDuration) Add(t time.Time) time.Time

Add adds the duration to a timestamp

func (StandardDuration) EndTime added in v0.44.0

func (d StandardDuration) EndTime(t time.Time) time.Time

func (StandardDuration) EstimateNative added in v0.41.0

func (d StandardDuration) EstimateNative() (time.Duration, bool)

EstimateNative estimates the duration as a native Go duration.

func (StandardDuration) Sub added in v0.37.0

func (d StandardDuration) Sub(t time.Time) time.Time

Sub subtracts the duration from a timestamp

func (StandardDuration) Truncate added in v0.41.0

func (d StandardDuration) Truncate(t time.Time, firstDayOfWeek, firstMonthOfYear int) time.Time

Truncate truncates a timestamp to the duration. It keeps the timezone of the timestamp. It only partially supports durations with multiple components (e.g. P1Y3M): it will truncate by the first component only. TODO: Is there a well-defined way to truncate by multiple components? TODO: Can this be merged with timeutil.TruncateTime? timeutil returns UTC values, whereas this returns in the same tz as the input time.

type TruncToDateDuration added in v0.37.0

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

func (TruncToDateDuration) Add added in v0.37.0

func (TruncToDateDuration) EstimateNative added in v0.41.0

func (d TruncToDateDuration) EstimateNative() (time.Duration, bool)

func (TruncToDateDuration) Sub added in v0.37.0

func (TruncToDateDuration) SubWithUnit added in v0.44.0

func (d TruncToDateDuration) SubWithUnit(t time.Time, unit int) time.Time
