Functions

func DeleteAllSpace

func DeleteAllSpace(str string) string

DeleteAllSpace 利用正则表达式压缩字符串，去除空格或制表符

func GetGuid() string

func RandInt

func RandInt(n int) int

func RandStringRunes

func RandStringRunes(n int, t StringType) string

func ReverseString

func ReverseString(s string) string

ReverseString 反转字符串

func StrToSlice

func StrToSlice(str string, split string) (result []string)

StrToSlice 将字符串按指定字符串打散成字符串切片

Types

type BuilderEx

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

A BuilderEx is used to efficiently build a string using Write methods. It minimizes memory copying. The zero value is ready to use. Do not copy a non-zero BuilderEx.

func (*BuilderEx) Cap

func (b *BuilderEx) Cap() int

Cap returns the capacity of the builder's underlying byte slice. It is the total space allocated for the string being built and includes any bytes already written.

func (*BuilderEx) Clear

func (b *BuilderEx) Clear()

func (*BuilderEx) Grow

func (b *BuilderEx) Grow(n int)

Grow grows b's capacity, if necessary, to guarantee space for another n bytes. After Grow(n), at least n bytes can be written to b without another allocation. If n is negative, Grow panics.

func (*BuilderEx) Len

func (b *BuilderEx) Len() int

Len returns the number of accumulated bytes; b.Len() == len(b.String()).

func (*BuilderEx) Reset

func (b *BuilderEx) Reset()

Reset resets the BuilderEx to be empty.

func (*BuilderEx) String

func (b *BuilderEx) String() string

String returns the accumulated string.

func (*BuilderEx) Write

func (b *BuilderEx) Write(p []byte) (int, error)

Write appends the contents of p to b's buffer. Write always returns len(p), nil.

func (*BuilderEx) WriteByte

func (b *BuilderEx) WriteByte(c byte) error

WriteByte appends the byte c to b's buffer. The returned error is always nil.

func (*BuilderEx) WriteRune

func (b *BuilderEx) WriteRune(r rune) (int, error)

WriteRune appends the UTF-8 encoding of Unicode code point r to b's buffer. It returns the length of r and a nil error.

func (*BuilderEx) WriteString

func (b *BuilderEx) WriteString(s string) (int, error)

WriteString appends the contents of s to b's buffer. It returns the length of s and a nil error.

type ObjectId

type ObjectId string

ObjectId is a unique ID identifying a BSON value. It must be exactly 12 bytes long. MongoDB objects by default have such a property set in their "_id" property.

http://www.mongodb.org/display/DOCS/Object+IDs

func NewObjectId

func NewObjectId() ObjectId

NewObjectId returns a new unique ObjectId. 4byte 时间， 3byte 机器ID 2byte pid 3byte 自增ID

func (ObjectId) Hex

func (id ObjectId) Hex() string

Hex returns a hex representation of the ObjectId. 返回16进制对应的字符串

type StringType

type StringType int

const (
	Letter StringType = iota
	Num
	All
)
