Types

type By

type By[R record.Record] interface {
	Less(a, b R) bool

	// String must return human readable format for debug
	String() string
}

By is base interface for sorting.

func ByScalar

func ByScalar[R record.Record](s Scalar[R]) By[R]

ByScalar create sorting by int64 values.

type ByWithOrder

type ByWithOrder[R record.Record] interface {
	By[R]
	// contains filtered or unexported methods
}

ByWithOrder wrapper for By interface with order (ASC/DESC) ByWithOrder can't be implemented in user level, use Asc() and Desc() for wrap By implementation.

func Asc

func Asc[R record.Record](by By[R]) ByWithOrder[R]

Asc wrap by for sorting in ASC (Ascending) direction.

func Desc

func Desc[R record.Record](by By[R]) ByWithOrder[R]

Desc wrap by for sorting in DESC (Descending) direction.

type Scalar

type Scalar[R record.Record] interface {
	Calc(item R) int64
}

Scalar is a special case for sorting by comparing int64 values.
