Types

type Rand

type Rand struct {
	// contains filtered or unexported fields
}

func NewRand

func NewRand() *Rand

func (*Rand) B

func (r *Rand) B(n int) []byte

B retrieves and returns random bytes of given length `n`.

func (*Rand) D

func (r *Rand) D(min, max time.Duration) time.Duration

D returns a random time.Duration between min and max: [min, max].

func (*Rand) GetDigits

func (r *Rand) GetDigits(n int) string

GetDigits returns a random str which contains only digits, and its length is `n`.

func (*Rand) GetLetters

func (r *Rand) GetLetters(n int) string

GetLetters returns a random str which contains only letters, and its length is `n`.

func (*Rand) GetString

func (r *Rand) GetString(s string, n int) string

GetString randomly picks and returns `n` count of chars from given str `s`. It also supports unicode str like Chinese/Russian/Japanese, etc.

func (*Rand) GetSymbols

func (r *Rand) GetSymbols(n int) string

GetSymbols returns a random str which contains only symbols, and its length is `n`.

func (*Rand) Intn

func (r *Rand) Intn(max int) int

func (*Rand) Meet

func (r *Rand) Meet(num, total int) bool

Meet randomly calculate whether the given probability `num`/`total` is met.

func (*Rand) MeetProb

func (r *Rand) MeetProb(prob float32) bool

MeetProb randomly calculate whether the given probability is met.

func (*Rand) N

func (r *Rand) N(min, max int) int

N returns a random int between min and max: [min, max]. The `min` and `max` also support negative numbers.

func (*Rand) Perm

func (r *Rand) Perm(n int) []int

Perm returns, as a slice of n int numbers, a pseudo-random permutation of the integers [0,n). TODO performance improving for large slice producing.

func (*Rand) S

func (r *Rand) S(n int, symbols ...bool) string

S returns a random str which contains digits and letters, and its length is `n`. The optional parameter `symbols` specifies whether the result could contain symbols, which is false in default.

type Str

type Str struct {
	// contains filtered or unexported fields
}

func NewStr

func NewStr(original string) *Str

func (*Str) PadLeftZeros

func (r *Str) PadLeftZeros(length int) (string, error)

PadLeftZeros 前置补零

func (*Str) PadRightZeros

func (r *Str) PadRightZeros(length int) (string, error)

PadRightZeros 后置补零

type TerminalLog

type TerminalLog struct {
	// contains filtered or unexported fields
}

func NewTerminalLog

func NewTerminalLog(format string) *TerminalLog

NewTerminalLog 实例化：控制台日志

func (*TerminalLog) Error

func (r *TerminalLog) Error(v ...any)

Error 打印错误并终止程序

func (*TerminalLog) Info

func (r *TerminalLog) Info(v ...any)

Info 打印日志行

func (*TerminalLog) Success
