Functions ¶
func Bool ¶
func Bool(i interface{}) bool
Bool converts <i> to bool. It returns false if <i> is: false, "", 0, "false", "off", empty slice/map.
func Convert ¶
func Convert(i interface{}, t string, params ...interface{}) interface{}
Convert converts the variable <i> to the type <t>, the type <t> is specified by string. The unnecessary parameter <params> is used for additional parameter passing.
func Duration ¶
Duration converts <i> to time.Duration. If <i> is string, then it uses time.ParseDuration to convert it. If <i> is numeric, then it converts <i> as nanoseconds.
func GTime ¶
GTime converts <i> to *gtime.Time. The parameter <format> can be used to specify the format of <i>. If no <format> given, it converts <i> using gtime.NewFromTimeStamp if <i> is numeric, or using gtime.StrToTime if <i> is string.
func Interfaces ¶
func Interfaces(i interface{}) []interface{}
Interfaces converts <i> to []interface{}.
func Map ¶
Map converts any variable <i> to map[string]interface{}. If the parameter <i> is not a map type, then the conversion will fail and returns nil. If <i> is a struct object, the second parameter <tags> specifies the most priority tags that will be detected, otherwise it detects the tags in order of: gconv, json.
func Maps ¶
func Maps(i interface{}) []map[string]interface{}
Maps converts <i> to []map[string]interface{}.
func Struct ¶
Struct maps the params key-value pairs to the corresponding struct object properties. The third parameter mapping is unnecessary, indicating the mapping between the custom name and the attribute name.
Note:
- The <params> can be any type of may/struct, usually a map;
- The second parameter <objPointer> should be a pointer to the struct object;
- Only the public attributes of struct object can be mapped;
- If <params> is a map, the key of the map <params> can be lowercase. It will automatically convert the first letter of the key to uppercase in mapping procedure to do the matching. If it does not match, ignore the key;
