Module datafusion_physical_expr::intervals::interval_aritmetic

Interval arithmetic library

Structs

• Interval
  This type represents an interval, which is used to calculate reliable bounds for expressions. Currently, we only support addition and subtraction, but more capabilities will be added in the future. Upper/lower bounds having NULL values indicate an unbounded side. For example; [10, 20], [10, ∞), (-∞, 100] and (-∞, ∞) are all valid intervals.
• IntervalBound
  This type represents a single endpoint of an Interval. An endpoint can be open or closed, denoting whether the interval includes or excludes the endpoint itself.

Functions

• apply_operator
• cardinality_ratio
  This function computes the cardinality ratio of the given intervals.
