Struct `std.datetime.interval.NegInfInterval`

Represents an interval of time which has negative infinity as its starting point.



struct NegInfInterval(TP)
;

Any ranges which iterate over a NegInfInterval are infinite. So, the main purpose of using NegInfInterval is to create an infinite range which starts at negative infinity and goes to a fixed end point. Iterate over it in reverse.

Constructors

Name	Description
`this`

Properties

Name	Type	Description
`end`[get]	`TP`	The end point of the interval. It is excluded from the interval.
`end`[set]	`TP`	The end point of the interval. It is excluded from the interval.

Methods

Name	Description
`bwdRange`	Returns a range which iterates backwards over the interval, starting at `end`, using func to generate each successive time point.
`contains`	Whether the given time point is within this interval.
`contains`	Whether the given interval is completely within this interval.
`contains`	Whether the given interval is completely within this interval.
`contains`	Whether the given interval is completely within this interval.
`expand`	Expands the interval forwards and/or backwards in time. Effectively, it adds the given number of months/years to end.
`expand`	Expands the interval forwards in time. Effectively, it does `end += duration`.
`intersection`	Returns the intersection of two intervals
`intersection`	Returns the intersection of two intervals
`intersection`	Returns the intersection of two intervals
`intersects`	Whether the given interval overlaps this interval.
`intersects`	Whether the given interval overlaps this interval.
`intersects`	Whether the given interval overlaps this interval.
`isAdjacent`	Whether the given interval is adjacent to this interval.
`isAdjacent`	Whether the given interval is adjacent to this interval.
`isAdjacent`	Whether the given interval is adjacent to this interval.
`isAfter`	Whether this interval is after the given time point.
`isAfter`	Whether this interval is after the given interval and does not intersect it.
`isAfter`	Whether this interval is after the given interval and does not intersect it.
`isAfter`	Whether this interval is after the given interval and does not intersect it.
`isBefore`	Whether this interval is before the given time point.
`isBefore`	Whether this interval is before the given interval and does not intersect it.
`isBefore`	Whether this interval is before the given interval and does not intersect it.
`isBefore`	Whether this interval is before the given interval and does not intersect it.
`merge`	Returns the union of two intervals
`merge`	Returns the union of two intervals
`opAssign`
`shift`	Shifts the `end` of this interval forward or backwards in time by the given duration (a positive duration shifts the interval forward; a negative duration shifts it backward). Effectively, it does `end += duration`.
`shift`	Shifts the `end` of this interval forward or backwards in time by the given number of years and/or months (a positive number of years and months shifts the interval forward; a negative number shifts it backward). It adds the years the given years and months to end. It effectively calls `add!"years"()` and then `add!"months"()` on end with the given number of years and months.
`span`	Returns an interval that covers from the earliest time point of two intervals up to (but not including) the latest time point of two intervals.
`span`	Returns an interval that covers from the earliest time point of two intervals up to (but not including) the latest time point of two intervals.
`toString`	Converts this interval to a string.
