🪐 Universal external Golang utilities, implementations, and even experimental coding patterns, designs
Development
Clone the repository:
git clone https://github.com/nekomeowww/xo
cd xo
Prepare the dependencies:
go mod tidy
[!NOTE] If you want to work with
protobufs/testpbdirectory and generate new Golang code, you need to install thebuftool.cd protobufs buf dep update buf generate --path ./testpb

func (SomeTable) Fields() []ent.Field {
return []ent.Field{
field.
String("payload").
ValueScanner(utils.ProtoValueScanner[somepb.YourMessage]{}).
GoType(&somepb.YourMessage{}).
SchemaType(map[string]string{
dialect.Postgres: "jsonb",
dialect.MySQL: "json",

}),
}
}
func (ProtoValueScanner[T]) FromValue ¶ added in v1.9.7
func (s ProtoValueScanner[T]) FromValue(value driver.Value) (vt *T, err error)
FromValue returns the field instance from the ScanValue above after the database value was scanned.
func (ProtoValueScanner[T]) ScanValue ¶ added in v1.9.7
func (s ProtoValueScanner[T]) ScanValue() field.ValueScanner
ScanValue returns a new ValueScanner that functions as an intermediate result between database value and GoType value. For example, sql.NullString or sql.NullInt.
