First of all I have one structure:
type times map[time.Time]struct{}
I need to write for it Marshal
/Unmarshal
methods for json converting. I've wrote MarshalJSON
method, but do not understand how to write UnmarshalJSON
method.
func (ts times) keys() []time.Time {
res := make([]time.Time, 0, len(ts))
for key := range ts {
res = append(res, key)
}
return res
}
func (ts times) MarshalJSON() ([]byte, error) {
return json.Marshal(ts.keys())
}
func (ts *times) UnmarshalJSON(b []byte) (error) {
// ????
}
Any idea?
