Variables

var (
	AllPrivileges     = List{ALL, CREATE, DROP, GRANT, SELECT, INSERT, DELETE, UPDATE, USAGE, ZONECONFIG}
	ReadData          = List{GRANT, SELECT}
	ReadWriteData     = List{GRANT, SELECT, INSERT, DELETE, UPDATE}
	DBTablePrivileges = List{ALL, CREATE, DROP, GRANT, SELECT, INSERT, DELETE, UPDATE, ZONECONFIG}
	SchemaPrivileges  = List{ALL, GRANT, CREATE, USAGE}
	TypePrivileges    = List{ALL, GRANT, USAGE}
)

Predefined sets of privileges.

var ByName = map[string]Kind{
	"ALL":        ALL,
	"CREATE":     CREATE,
	"DROP":       DROP,
	"GRANT":      GRANT,
	"SELECT":     SELECT,
	"INSERT":     INSERT,
	"DELETE":     DELETE,
	"UPDATE":     UPDATE,
	"ZONECONFIG": ZONECONFIG,
	"USAGE":      USAGE,
}

ByName is a map of string -> kind value.

var ByValue = [...]Kind{
	ALL, CREATE, DROP, GRANT, SELECT, INSERT, DELETE, UPDATE, USAGE, ZONECONFIG,
}

ByValue is just an array of privilege kinds sorted by value.

Types

type Kind

type Kind uint32

Kind defines a privilege. This is output by the parser, and used to generate the privilege bitfields in the PrivilegeDescriptor.

const (
	ALL Kind
	CREATE
	DROP
	GRANT
	SELECT
	INSERT
	DELETE
	UPDATE
	USAGE
	ZONECONFIG
)

List of privileges. ALL is specifically encoded so that it will automatically pick up new privileges.

func (Kind) Mask

func (k Kind) Mask() uint32

Mask returns the bitmask for a given privilege.

func (Kind) String

func (i Kind) String() string

type List

type List []Kind

List is a list of privileges.

func ListFromStrings

func ListFromStrings(strs []string) (List, error)

ListFromStrings takes a list of strings and attempts to build a list of Kind. We convert each string to uppercase and search for it in the ByName map. If an entry is not found in ByName, an error is returned.

func (List) Format

func (pl List) Format(buf *bytes.Buffer)

Format prints out the list in a buffer. This keeps the existing order and uses ", " as separator.

func (List) Len

func (pl List) Len() int

Len, Swap, and Less implement the Sort interface.

func (List) Less

func (pl List) Less(i, j int) bool

func (List) SortedNames

func (pl List) SortedNames() []string

SortedNames returns a list of privilege names in sorted order.

func (List) SortedString

func (pl List) SortedString() string

SortedString is similar to String() but returns privileges sorted by name and uses "," as separator.

func (List) String

func (pl List) String() string

String implements the Stringer interface. This keeps the existing order and uses ", " as separator.

func (List) Swap

func (pl List) Swap(i, j int)

func (List) ToBitField

func (pl List) ToBitField() uint32

ToBitField returns the bitfield representation of a list of privileges.

type ObjectType

type ObjectType string

ObjectType represents objects that can have privileges.

const (
	// Any represents any object type.
	Any ObjectType = "any"
	// Database represents a database object.
	Database ObjectType = "database"
	// Schema represents a schema object.
	Schema ObjectType = "schema"
	// Table represents a table object.
	Table ObjectType = "table"
	// Type represents a type object.
	Type ObjectType = "type"
)
