go get github.com/hamba/slicesContains is a generic slice contains function.
Supports: bool, string, int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64, float32, float64
slice := []string{"foo", "bar"}
v := "bar"
fmt.Println(slices.Contains(slice, v))
// Outputs: trueGreaterOf returns a greater function for the given slice type for slice sorting.
Supports: string, int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64, float32, float64
slice := []string{"foo", "bar"}
sort.Slice(slice, slices.GreaterOf(slice))
fmt.Println(slice)
// Outputs: [foo bar]LesserOf returns a lesser function for the given slice type for slice sorting.
Supports: string, int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64, float32, float64
slice := []string{"foo", "bar"}
sort.Slice(slice, slices.LesserOf(slice))
fmt.Println(slice)
// Outputs: [bar foo]Intersect returns the intersection of 2 slices.
Supports: string, int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64, float32, float64

fmt.Println(slices.Intersect(slice, other))
// Outputs: [bar baz]Except returns the all elements in the first slice that are not in the second.
