Intervals

This package defines:

• AbstractInterval, along with its subtypes:
  • Interval{T,L,R}, which represents a non-iterable range between two endpoints of type T with left/right bounds types respectively being L and R
  • AnchoredInterval{P,T,L,R}, which represents a non-iterable range defined by a single value anchor::T and the value type P which represents the span of the range. Left/right bounds types are specifed by L and R respectively
    • HourEnding, a type alias for AnchoredInterval{Hour(-1)}
    • HourBeginning, a type alias for AnchoredInterval{Hour(1)}
    • HE and HB, pseudoconstructors for HourEnding and HourBeginning that round the anchor up (HE) or down (HB) to the nearest hour
• Bound, abstract type for all possible bounds type classifications:
  • Closed, indicating the endpoint value of the interval is included
  • Open, indicating the endpoint value of the interval is not included
  • Unbounded, indicating the endpoint value is effectively infinite
