Functions ¶
func Contain ¶
func Contain(item interface{}, slice interface{}) bool
Contain checks whether a element is in a slice (same type)
func CutInt ¶
CutInt removes a sub-slice from start(inclusive in removed slice) to end (exclusive in remve slice) from original slice
func CutStr ¶
CutStr removes a sub-slice from start(inclusive in removed slice) to end (exclusive in remve slice) from original slice
func DeduplicateInt ¶
DeduplicateInt de-duplicates a slice in place
func DeduplicateStr ¶
DeduplicateStr de-duplicates a slice in place
func ExpandInt ¶
ExpandInt expands capacity of slice from `start` (inclusive) to `end` exclusive point.
func ExpandStr ¶
ExpandStr expands capacity of slice from `start` (inclusive) to `end` exclusive point.
func FilterIntNoAllocate ¶
FilterStrNoAllocate filters a slice without allocating. This trick uses the fact that a slice shares the same backing array and capacity as the original, so the storage is reused for the filtered slice. Of course, the original contents are modified.
func FilterStrNoAllocate ¶
FilterStrNoAllocate filters a slice without allocating. This trick uses the fact that a slice shares the same backing array and capacity as the original, so the storage is reused for the filtered slice. Of course, the original contents are modified.
func InsertVecInt ¶
InsertVecInt inserts a slice (`b`) to origin slice (`a`) at specified index point
func InsertVecStr ¶
InsertVecStr inserts a slice (`b`) to origin slice (`a`) at specified index point
func PopFrontInt ¶
PopFrontInt pops the first item from the slice (shift)
func PopFrontStr ¶
PopFrontStr pops the first item from the slice (shift)
func PushFrontInt ¶
PushFrontInt pushes an item to the front of a slice (unshift)
func PushFrontStr ¶
PushFrontStr pushes an item to the front of a slice (unshift)
func Reverse ¶
func Reverse(s interface{}) (retVal interface{})
Reverse reverses any slice Source: https://stackoverflow.com/questions/28058278
func ReverseInt ¶
ReverseInt replaces the contents of a slice with the same elements but in reverse order
func ReverseLRInt ¶
ReverseLRInt does the same as ReverseInt except with 2 indices
func ReverseLRStr ¶
ReverseLRStr does the same as ReverseStr except with 2 indices
func ReverseStr ¶
ReverseStr replaces the contents of a slice with the same elements but in reverse order
func ShuffleInt ¶
ShuffleInt shuffles a slice using Fisher–Yates algorithm Since go1.10, this is available at math/rand.Shuffle (https://godoc.org/math/rand#Shuffle)
func ShuffleStr ¶
ShuffleStr shuffles a slice using Fisher–Yates algorithm Since go1.10, this is available at math/rand.Shuffle (https://godoc.org/math/rand#Shuffle)
