Types

type Comparable

type Comparable[T any] interface {
	Compare(T) int
}

包含了CompareLess和IsEqual,尽量统一使用Comparable

type ComparableKey

type ComparableKey[T CompareKey[V], V constraints.Ordered] interface {
	Compare(T) int
}

type CompareFunc

type CompareFunc[T any] func(T, T) int

type CompareKey

type CompareKey[T constraints.Ordered] interface {
	CompareKey() T
}

下面不推荐使用 合理使用,如int, 正序 return v,倒序return -v,并适当考虑边界值问题

type CompareLess

type CompareLess[T any] interface {
	Less(T) bool
}

type CompareNumKey

type CompareNumKey[T constraintsi.Number] interface {
	CompareKey() T
}

可以直接用-号

type EqualKey

type EqualKey[T comparable] interface {
	EqualKey() T
}

type GTValue

type GTValue[T constraints.Ordered] struct {
	Value T
}

func (GTValue[T]) Compare

func (a GTValue[T]) Compare(b GTValue[T]) bool

type IsEqual

type IsEqual[T any] interface {
	Equal(T) bool
}

type LTValue

type LTValue[T constraints.Ordered] struct {
	Value T
}

func (LTValue[T]) Compare

func (a LTValue[T]) Compare(b GTValue[T]) bool

type LessFunc

type LessFunc[T any] func(T, T) bool
