Types ¶
type BoolSlice ¶
type BoolSlice []bool
BoolSlice makes easy to handle JSON encoded bool lists stored at database's text fields(like VARCHAR,CHAR,TEXT) and blob fields
type CompactJSONStr ¶
type CompactJSONStr json.RawMessage
CompactJSONStr is same as JSONStr except, whitespaces are remove from JSON formatted data while saving to database. It is useless if data is hold in database specific json typed field(like PostgreSQL's JSONB field). NullCompactJSONStr is nullable version of CompactJSONStr.
CompactJSONStr is `json.RawMessage` (`[]byte`) type, adding `Value()` and `Scan()` methods for db access and `MarshalJSON`, `UnmarshalJSON` for json serializing.
This type make use of DB binary or string fields like a JSON container. DB field type can be text types like CHAR, STRING, CHARACTER VARYING, TEXT or binary types like JSONB, BYTEA, BLOB...
JSON data is hold as "compacted" mode in database.
For performance binary db field use is advised.
func (CompactJSONStr) MarshalJSON ¶
func (js CompactJSONStr) MarshalJSON() ([]byte, error)
MarshalJSON returns JSON encoding
func (*CompactJSONStr) Scan ¶
func (js *CompactJSONStr) Scan(src interface{}) error
Scan stores the value as CompactJSONStr. Value can be string, []byte or or nil.
func (*CompactJSONStr) Unmarshal ¶
