Float64Comparator provides a basic comparison on float64

func GenericComparator

func GenericComparator[T constraints.Ordered](a, b T) int

func Int16Comparator

func Int16Comparator(a, b interface{}) int

Int16Comparator provides a basic comparison on int16

func Int32Comparator

func Int32Comparator(a, b interface{}) int

Int32Comparator provides a basic comparison on int32

func Int64Comparator

func Int64Comparator(a, b interface{}) int

Int64Comparator provides a basic comparison on int64

func Int8Comparator

func Int8Comparator(a, b interface{}) int

Int8Comparator provides a basic comparison on int8

func IntComparator

func IntComparator(a, b interface{}) int

IntComparator provides a basic comparison on int

func RuneComparator

func RuneComparator(a, b interface{}) int

RuneComparator provides a basic comparison on rune

func Sort

func Sort[T constraints.Ordered](values []T, comparator Comparator[T])

Sort sorts values (in-place) with respect to the given comparator.

Uses Go's sort (hybrid of quicksort for large and then insertion sort for smaller slices).

func StringComparator

func StringComparator(a, b interface{}) int

StringComparator provides a fast comparison on strings

func TimeComparator

func TimeComparator(a, b interface{}) int

TimeComparator provides a basic comparison on time.Time

func ToString

func ToString(value interface{}) string

ToString converts a value to string.

func UInt16Comparator

func UInt16Comparator(a, b interface{}) int

UInt16Comparator provides a basic comparison on uint16

func UInt32Comparator

func UInt32Comparator(a, b interface{}) int

UInt32Comparator provides a basic comparison on uint32

func UInt64Comparator

func UInt64Comparator(a, b interface{}) int

UInt64Comparator provides a basic comparison on uint64

func UInt8Comparator

func UInt8Comparator(a, b interface{}) int

UInt8Comparator provides a basic comparison on uint8

func UIntComparator

func UIntComparator(a, b interface{}) int

UIntComparator provides a basic comparison on uint

Types

type Comparator

type Comparator[T constraints.Ordered] func(a, b T) int

Comparator will make type assertion (see IntComparator for example), which will panic if a or b are not of the asserted type.

Should return a number:

negative , if a < b
zero     , if a == b
positive , if a > b
