stdx::interval, a library for intervals on totally ordered sets Eric Hughes, Meadhbh Hamrick ## I n brief stdx::interval implements the mathematical sense of an interval on a totally ordered set. The library reasons reasons about intervals as sets, not as interval expressions. The library is header-only and targets C++20. It is available under the MIT License. ## Features ## Predicates Membership. Determine if a point \infty,b](-\infty,b)(-\infty,+\infty) Generic. The library handles the differences between discrete (e.g. int and other integral types) and continuous (string
