func RandomAlphaOrNumeric ​

go
func RandomAlphaOrNumeric(count uint, letters, numbers bool) string

Creates a random string whose length is the number of characters specified.

Characters will be chosen from the set of alpha-numeric characters as indicated by the arguments.

Param count - the length of random string to create Param letters - if true, generated string will include

alphabetic characters

Param numbers - if true, generated string will include

numeric characters

func RandomAlphabetic ​

go
func RandomAlphabetic(count uint) string

Creates a random string whose length is the number of characters specified. Characters will be chosen from the set of alphabetic characters.

func RandomAlphanumeric ​

go
func RandomAlphanumeric(count uint) string

Creates a random string whose length is the number of characters specified. Characters will be chosen from the set of alpha-numeric characters.

func RandomAscii ​

go
func RandomAscii(count uint) string

Creates a random string whose length is the number of characters specified.

Characters will be chosen from the set of characters whose ASCII value is between 32 and 126 (inclusive).

func RandomInt ​

go
func RandomInt(min, max int) int

RandomInt return a random int at the [min, max] Intn returns, as an int, a non-negative pseudo-random number in the half-open interval [0,n] from the default Source. It panics if n <= 0

Usage:

RandomInt(10, 99)
RandomInt(100, 999)
RandomInt(1000, 9999)

func RandomNumber ​

go
func RandomNumber(len int) string

RandomNumber func

func RandomNumeric ​

go
func RandomNumeric(count uint) string

Creates a random string whose length is the number of characters specified. Characters will be chosen from the set of numeric characters.

func RandomSpec0 ​

go
func RandomSpec0(count uint, start, end int, letters, numbers bool, chars []rune) string

Creates a random string based on a variety of options, using supplied source of randomness.

If start and end are both 0, start and end are set to ' ' and 'z', the ASCII printable characters, will be used, unless letters and numbers are both false, in which case, start and end are set to 0 and math.MaxInt32.

If set is not nil, characters between start and end are chosen.

This method accepts a user-supplied rand.Rand instance to use as a source of randomness. By seeding a single rand.Rand instance with a fixed seed and using it for each call, the same random sequence of strings can be generated repeatedly and predictably.

func RandomSpec1 ​

go
func RandomSpec1(count uint, start, end int, letters, numbers bool) string

Creates a random string whose length is the number of characters specified.

Characters will be chosen from the set of alpha-numeric characters as indicated by the arguments.

Param count - the length of random string to create Param start - the position in set of chars to start at Param end - the position in set of chars to end before Param letters - if true, generated string will include

alphabetic characters

Param numbers - if true, generated string will include

numeric characters

func RandomString ​

go
func RandomString(count uint) string

func RandomStringSpec0 ​

go
func RandomStringSpec0(count uint, set []rune) string

func RandomStringSpec1 ​

go
func RandomStringSpec1(count uint, set string) string
