Abstract types​

These types are used in definitions of polymorphic (generic) functions that can be applied to a broad range of types.

type

anytype

Generic type.

It is a placeholder used in cases where no specific type requirements are needed, such as defining polymorphic parameters in functions and operators.

type

anyscalar

Abstract base scalar type.

All scalar types are derived from this type.

type

anyenum

Abstract base enumerated type.

All enum types are derived from this type.

type

anytuple

Generic tuple.

Similarly to anytype it denotes a generic tuple without going into details of what the components are. Just as with anytype, this is useful when defining polymorphic parameters in functions and operators.

Abstract Numeric Types​

There are a number of abstract numeric types extending anyscalar:

type

anyint

Abstract base scalar type for int16, int32, and int64.

type

anyfloat

Abstract base scalar type for float32 and float64.

type

anyreal

Abstract base scalar type for anyint, anyfloat, and decimal.
