Here's an example of a JSONB type:
```go
package mypackage
import "github.com/gocql/gocql"
var typeJSONB gocql.Type = 0x0080
func init() {
gocql.RegisterType(typeJSONB, "jsonb", JSONBCQLType{})
}
// JSONBTypeInfo implements the gocql.TypeInfo interface
type JSONBTypeInfo struct {
proto byte
}
// Type implements the gocql.TypeInfo interface
func (j JSONBTypeInfo) Type() gocql.Type {
return typeJSONB
}
// Version implements the gocql.TypeInfo interface
func (j JSONBTypeInfo) Version() byte {
return j.proto
}
// Custom implements the gocql.TypeInfo interface
func (j JSONBTypeInfo) Custom() string {
return ""
}
// New implements the gocql.TypeInfo interface
func (j JSONBTypeInfo) New() interface{} {
return new([]byte)
}
// NewWithError implements the gocql.TypeInfo interface
func (j JSONBTypeInfo) NewWithError() (interface{}, error) {
return new([]byte), nil
}
// JSONBCQLType implements the gocql.CQLType interface
type JSONBCQLType struct {
}
// TypeInfo implements the gocql.CQLType interface
func (j JSONBCQLType) TypeInfo(proto int) gocql.TypeInfo {
return JSONBTypeInfo{proto: byte(proto)}
}
// Marshal implements the gocql.CQLType interface
func (j JSONBCQLType) Marshal(info gocql.TypeInfo, value interface{})
([]byte, error) {
return gocql.Marshal(gocql.NewNativeType(info.Version(),
gocql.TypeBlob, ""), value)
}
// Unmarshal implements the gocql.CQLType interface
func (j JSONBCQLType) Unmarshal(info gocql.TypeInfo, value []byte, dest
interface{}) error {
return gocql.Unmarshal(gocql.NewNativeType(info.Version(),
gocql.TypeBlob, ""), value, dest)
}
```
