Overview

Package sliceutil provides methods for working with slices

Index

• func Contains(slice []string, value string) bool
• func Copy(slice []string) []string
• func CopyFloats(slice []float64) []float64
• func CopyInts(slice []int) []int
• func Deduplicate(slice []string) []string
• func ErrorToString(data []error) []string
• func Exclude(slice []string, items ...string) []string
• func Index(slice []string, item string) int
• func IntToInterface(data []int) []interface{}
• func StringToError(data []string) []error
• func StringToInterface(data []string) []interface{}

Examples

• Copy
• CopyFloats
• CopyInts
• Deduplicate
• ErrorToString
• Exclude
• Index
• IntToInterface
• StringToInterface

Functions

func Contains

func Contains(slice []string, value string) bool

Contains checks if string slice contains some value

func Copy

func Copy(slice []string) []string

Copy creates copy of given slice

Example

s1 := []string{"A", "B", "C"}
s2 := Copy(s1)

fmt.Printf("%v", s2)

Output:

[A B C]

func CopyFloats

func CopyFloats(slice []float64) []float64

CopyFloats creates copy of given slice

Example

s1 := []float64{1.0, 5.0}
s2 := CopyFloats(s1)

fmt.Printf("%v", s2)

Output:

[1 5]

func CopyInts

func CopyInts(slice []int) []int

CopyInts creates copy of given slice

Example

s1 := []int{1, 2, 3}
s2 := CopyInts(s1)

fmt.Printf("%v", s2)

Output:

[1 2 3]

func Deduplicate

func Deduplicate(slice []string) []string

Deduplicate removes duplicates from slice. Slice must be sorted before deduplication.

Example

s := []string{"A", "A", "A", "B", "C", "C", "D"}

fmt.Println(Deduplicate(s))

Output:

[A B C D]

func ErrorToString

func ErrorToString(data []error) []string

ErrorToString converts slice with errors to slice with strings

Example

s := []error{fmt.Errorf("error1")}

fmt.Printf("%v", ErrorToString(s))

Output:

[error1]

func Exclude

func Exclude(slice []string, items ...string) []string

Exclude removes items from slice

Example

s := []string{"A", "B", "C", "D"}

fmt.Println(Exclude(s, "B", "D"))

Output:

[A C]

func Index

func Index(slice []string, item string) int

Index returns index of given item in a slice or -1 otherwise

Example

s := []string{"A", "B", "C"}

fmt.Println(Index(s, "C"))
fmt.Println(Index(s, "D"))

Output:

2
-1

func IntToInterface

func IntToInterface(data []int) []interface{}

IntToInterface converts slice with ints to slice with interface{}

Example

s := []int{1, 2}

fmt.Printf("%v", IntToInterface(s))

Output:

[1 2]

func StringToError

func StringToError(data []string) []error

StringToError converts slice with strings to slice with errors

func StringToInterface

func StringToInterface(data []string) []interface{}

StringToInterface converts slice with strings to slice with interface{}

Example

s := []string{"A", "B"}

fmt.Printf("%v", StringToInterface(s))

Output:

[A B]
