type Equalities

type Equalities map[reflect.Type]reflect.Value

Equalities is a map from type to a function comparing two values of that type.

func EqualitiesOrDie

func EqualitiesOrDie(funcs ...interface{}) Equalities

For convenience, panics on errrors

func (Equalities) AddFunc

func (e Equalities) AddFunc(eqFunc interface{}) error

AddFunc uses func as an equality function: it must take two parameters of the same type, and return a boolean.

func (Equalities) AddFuncs

func (e Equalities) AddFuncs(funcs ...interface{}) error

AddFuncs is a shortcut for multiple calls to AddFunc.

func (Equalities) DeepDerivative

func (e Equalities) DeepDerivative(a1, a2 interface{}) bool

DeepDerivative is similar to DeepEqual except that unset fields in a1 are ignored (not compared). This allows us to focus on the fields that matter to the semantic comparison.

The unset fields include a nil pointer and an empty string.

func (Equalities) DeepEqual

func (e Equalities) DeepEqual(a1, a2 interface{}) bool

DeepEqual is like reflect.DeepEqual, but focused on semantic equality instead of memory equality.

It will use e's equality functions if it finds types that match.

An empty slice *is* equal to a nil slice for our purposes; same for maps.

Unexported field members cannot be compared and will cause an imformative panic; you must add an Equality function for these types.
