Struct IntervalLimit

pub struct IntervalLimit<T: Display + Clone + Hash + Ord> { /* private fields */ }

A struct that represents a “limit” in an interval.

In order to understand this struct, it is important to correctly recognize the distinction between limit and value. The limit is the value represented by this struct self, and the value represented by value is the limit value.

When a limit is “closed”, it means that the limit itself is not considered to be exceeded. An “open” limit means that it is considered to be exceeded.

An infinite limit is an unbounded limit, and we express this state by saying that value is Limitless. Infinite limits are always considered to be open. Conversely, a limit that is not an infinite limit (one whose value is not Limitless) is called a finite limit.

The lower limit represents the limit where values below (or below) the limit are considered to be exceeded, and the upper limit represents the limit where values above (or above) the limit are considered to be exceeded.

closed: if the limit is closed true lower: truefor the lower limit,false` for the upper limit value: limit value, in the case of Limitless, it indicates that there is no limit.
