Manager is the interface for providing privilege related operations.

func GetPrivilegeManager

func GetPrivilegeManager(ctx sessionctx.Context) Manager

GetPrivilegeManager gets Checker from context.

type VerificationInfo

type VerificationInfo struct {
	// InSandBoxMode indicates that the session will enter sandbox mode, and only execute statement for resetting password.
	InSandBoxMode bool

}

VerificationInfo records some information returned by Manager.ConnectionVerification
