CodoMetis.ValueRanges

v3.1.0

In-memory range and multirange types for .NET 10, mirroring PostgreSQL's six built-in range domains (int4range, int8range, numrange, daterange, tsrange, tstzrange). Each type is a discriminated union of five sealed variants (Finite, UnboundedStart, UnboundedEnd, EmptyRange, Infinity) with invalid states unrepresentable at compile time. Includes the full PostgreSQL interval algebra — Contains, Overlaps, IsAdjacentTo, Intersect, Union, Except, Complement — plus RangeSet<TRange, T> as an immutable, always-normalized multirange. All types implement IParsable<T> and IFormattable using PostgreSQL range literal syntax, and ship with System.Text.Json converters for direct use in ASP.NET Core APIs. No database dependency.
