Overview

Package constraints defines a set of useful constraints to be used with type parameters.

Types

type Complex

type Complex interface {
	~complex64 | ~complex128
}

Complex is a constraint that permits any complex numeric type. If future releases of Go add new predeclared complex numeric types, this constraint will be modified to include them.

type Float

type Float interface {
	~float32 | ~float64
}

Float is a constraint that permits any floating-point type. If future releases of Go add new predeclared floating-point types, this constraint will be modified to include them.

type Integer

type Integer interface {
	Signed | Unsigned
}

Integer is a constraint that permits any integer type. If future releases of Go add new predeclared integer types, this constraint will be modified to include them.

type Ordered

type Ordered interface {
	Integer | Float | ~string
}

Ordered is a constraint that permits any ordered type: any type that supports the operators < <= >= >. If future releases of Go add new ordered types, this constraint will be modified to include them.

type Signed

type Signed interface {
	~int | ~int8 | ~int16 | ~int32 | ~int64
}

Signed is a constraint that permits any signed integer type. If future releases of Go add new predeclared signed integer types, this constraint will be modified to include them.

type Unsigned

type Unsigned interface {
	~uint | ~uint8 | ~uint16 | ~uint32 | ~uint64 | ~uintptr
}

Unsigned is a constraint that permits any unsigned integer type. If future releases of Go add new predeclared unsigned integer types, this constraint will be modified to include them.
