### Type Traits that Describe the Properties of a Type

These traits are all value traits, which is to say the traits classes all inherit from integral_constant, and are used to access some numerical property of a type. Often this is a simple true or false Boolean value, but in a few cases may be some other integer value (for example when dealing with type alignments, or array bounds: see `alignment_of`, `rank` and `extent`).
