Types

type Charset

type Charset struct {
	Name             string
	DefaultCollation string
	Collations       map[string]*Collation
	Desc             string
	Maxlen           int
}

Charset is a charset. Now we only support MySQL.

type Collation

type Collation struct {
	ID          int
	CharsetName string
	Name        string
	IsDefault   bool
}

Collation is a collation. Now we only support MySQL.

func GetCollations

func GetCollations() []*Collation

GetCollations returns a list for all collations.

type Desc

type Desc struct {
	Name             string
	Desc             string
	DefaultCollation string
	Maxlen           int
}

Desc is a charset description.

func GetAllCharsets

func GetAllCharsets() []*Desc

GetAllCharsets gets all charset descriptions in the local charsets.

func GetCharsetDesc
